M SERIES MITSUBISHI MODULE PCB KIT

These Kits are to suit the older Mitsubishi Modules that some Hams or suppliers may have in stock.

Kits include PC Board, Instructions & all onboard components. We are not able to supply the M series Mitsubishi modules to suit these.

Use the M57762 KIT1 for M57735 Modules as they have the same pinout & bias.

With the M57727 Modules the bias & 1st DC supply pins 2 & 3 are the reverse of the M57762 & M57735 modules. So you can use either the M57716 or M57762 kits but you will have to change the component positions & cut a track on the PC board to suit.

Uses a Mitsubishi RA30H1317M module on a single PC board measuring 70 x 33mm, & is suitable for many projects including homebrew Transceivers & Transverters. The complete Kit includes all onboard components, double sided through hole plated PC board & construction notes. The Kit requires a heat sink, connectors, & miscellaneous hardware to complete.

The 2nd Harmonic from the RA30H1317M is only -25dBc so you will require a suitable Low Pass Filter. The PA Kit website shows how to build a suitable LPF.

Freq Range: 135 - 175MHz 
Output Power: 30Watts for 50mW Input 

Refer to the Mitsubishi website for the Data Sheet 

Please Note: You will require a very flat machined Heatsink for maximum reliability of the Module. Mini-Kits recommends the use of a P4 Pentium Fan assisted Heatsink. These can be found in computer recycling shops.

The RA30H1317M KIT1 can be used with the 60 Watt RA60H1317M module. Please refer to pricing for the 60W modules at the top of this Webpage.

Very comprehensive construction Notes are supplied with this Kit.

13/23CM PREAMPLIFIER KIT

Receive only pre amp built on G10 PC board. Suitable for use from 1200MHz to 2500MHz. Single stage uses a MGF1302 GasFET, dual stage uses a MGF1302 & ERA amplifier. Most receive setups including Satellite receivers will only usually require the single stage version.  If the preamplifier is to be mounted at the antenna with lossy cable, then the dual stage version should be used. Kit includes PC board & all on board components, requires box, connectors, & miscellaneous hardware to complete. For best Performance, only A SMA or N Type connector should be used on the input. SMA sockets are recommended for most applications. Also suitable for 1700MHz Weather Satellite use.

Specifications:

Dual Stage Prototypes tuned with an SMA input socket measured on a ( HP 8970B )
0.51dB Noise Figure & 33dB gain @ 1250MHz,

6M PREAMPLIFIER KIT

The Preamplifier has been designed to be relatively easy to construct, & only uses conventional components, ( No SMD ). The preamp can be centre frequency tuned from 40 to 60MHz, & is suitable for the 6M 50 - 54MHz Amateur band, & also suitable for low Band TV DX. The Preamp uses a low cost BF988A MesFET, which has good strong signal handing characteristics. The design incorporates RF changeover Relays & power supply decoupling so that power can be fed via the coaxial cable. It is simple to tune, & does not have any instability problems due to the use of a wideband output matching circuit. The Basic EME157 Kits include, PC board & all on board components, requires box, connectors, & miscellaneous hardware to complete.

The difference between the KITA & B is only the Relays. All RF changeover components are still supplied in the RX only Kit.

Specifications:

Prototype measured on a ( HP 8970B ) In a RF Screened Room.

Noise Figure <1.5dB ( Typically 1 .15dB @ 50MHz )
Gain ( Typically 15dB gain @ 50MHz ) Onboard 10dB Att

EME157 KIT WEB PAGE

IN STOCK
Please Note these are not Available Built

To connect the Antenna to the Preamp, & Preamp to the main feedline, we recommend the use of LMR240 cable with crimped BNC connectors. LMR240 is double shielded & has losses similar to RG213 cable, but has a much smaller 6mm diameter. Refer to our catalogue section3.pdf for LMR240 cable & connectors. The GME Masthead box will accept cables up to around 8mm in diameter. Therefore larger cables like RG8/213 cannot be used with this box. Larger cables would also place too much strain on the BNC sockets on the Preamplifier.

Please Note: Mini-Kits cannot be expected to take responsibility to make this product work on your Radio. We can only give guidance on how best to use this product. Many Radios may need modification for a TX voltage output to hard switch the preamp when using high power. Some Radios like the TS2000 do not feed +12 volts out the Antenna socket when the preamp switch is turned on, so either power & switching cables need to be run to the preamplifier, or a bias T will have to be constructed to feed power up the coaxial cable & connect to the Radios TX voltage output.

We don't expect that many will have any problems with the standard plastic Mast Head box compared to a shielded one. It may help only to keep some strong out of band Ham signals e.g. 2M or 70cm from entering the preamplifier & possibly overloading the Radios Receiver.

It is simple to tune, & does not have any instability problems due to the use of a wideband output matching circuit. The Basic EME157 Kits include, PC board & all on board components, requires box, connectors, & miscellaneous hardware to complete.

The difference between the KITA & B is only the Relays. All RF changeover components are still supplied in the RX only Kit.

To connect the Antenna to the Preamp, & Preamp to the main feedline, we recommend the use of LMR240 cable with crimped BNC connectors. LMR240 is double shielded & has losses similar to RG213 cable, but has a much smaller 6mm diameter. Refer to our catalogue section3.pdf for LMR240 cable & connectors. The GME Masthead box will accept cables up to around 8mm in diameter. Therefore larger cables like RG8/213 cannot be used with this box. Larger cables would also place too much strain on the BNC sockets on the Preamplifier.

Please Note: Mini-Kits cannot be expected to take responsibility to make this product work on your Radio. We can only give guidance on how best to use this product. Many Radios may need modification for a TX voltage output to hard switch the preamp when using high power. Some Radios like the TS2000 do not feed +12 volts out the Antenna socket when the preamp switch is turned on, so either power & switching cables need to be run to the preamplifier, or a bias T will have to be constructed to feed power up the coaxial cable & connect to the Radios TX voltage output.

We don't expect that many will have any problems with the standard plastic Mast Head box compared to a shielded one. It may help only to keep some strong out of band Ham signals e.g. 2M or 70cm from entering the preamplifier & possibly overloading the Radios Receiver.
