    2WATT 2400MHz MMIC 
    LINEAR AMPLIFIER MODULE

    This Modern High Performance 2.4GHz Power Amplifier uses a low cost PHEMT MMIC IC.  The MMIC provides a gain of 29dB & a saturated output power of more than +33dBm.  The MMIC requires minimal input & output matching to 50ohms, & makes other discrete PA designs using GaAs & HFETs etc, virtually obsolete for these power levels.  The PA is suitable for use with the current 2400MHz Transverter, & ATV Transmitter Kits.  The PA uses a high performance switching power supply along with bias protection circuitry, to provide high efficiency over a wide input voltage range, & has very low heat dissipation. Due to a Spectrum Analyzer being required to tune this Amplifier, it is for advanced constructors only.  The Module requires a heat sink, connectors & miscellaneous hardware to complete. 

    Specifications:

    PCB Dimensions: 37x47mm 
    Supply Voltage: 5v min to 14v max 
    Current 650mA @ 12v input
    Gain: 29dB Minimum
    Bandwidth: 2350 - 2450MHz 100MHz @ 1dB
    Output Power: 2Watts +33dBm @ 1dB Comp
    Input Power: 4dBm (2.5mW) for 33dBm (2Watt) Output.

    Please Note:  This PA is not suitable for Wireless Lan or 
    ( WiFi ) as it is not Bi-Directional.  You will require an Amateur Radio License or equivalent qualifications to purchase this Product.  This Product is only available to licensed operators in the 2400MHz band. It is Illegal to use this Product on unlicensed low power wireless Lan, video senders, video surveillance or any other LIPD device without a license.

    AMPLIFIER KIT
     
    A simple Receive only broadband untuned preamplifier built on the MMIC experimenters board.  Uses a Teflon PC board for low loss. Suitable for use as a wide band antenna amplifier for use on a scanning receiver or TV set.  The preamplifier uses an ERA3 MMIC which is suitable up to 3GHz.  Kit includes PC board & all on board components, requires box, connectors, & miscellaneous hardware to complete. The EME126 PC board is also suitable for use as an amplifier stage in a transmitter, or for experimenting with the MGA86576 HP Low Noise MMIC.

    Specifications:

    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 an 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.

    THE NEW VK5 2M 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 120 to 150MHz, & is suitable for the 2M 144 - 148MHz Amateur band, & also suitable for Weather Satellite reception on 137MHz. 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.

    The Mast Head Boxes ( Box 19 ) are now available with Nickel Sprayed Shielding for an extra $5.00

    If you want Nickel Spray Shielding then please add an extra $5.00 cost to all Kits & Built products that are supplied with the Mast Head Box.

    NEW IN STOCK

    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. 6M or 70cm from entering the preamplifier & possibly overloading the Radios Receiver.
