430MHz AM VIDEO TRANSMITTER KIT

High level Amplitude Modulated video transmitter for the 70cm Amateur band, built on a 71x100mm PC board. The design uses a sync stretcher & high level modulation to overcome the linearity requirements when transmitting TV signals, & produces up to 100mW, ( +20dBm ) output. The kit only requires 2 coils to be wound, & uses printed tuned inductors on the PC board for the output amplifier stages so it is easy to tune up. The complete Kit includes a professional plated PC board, & all onboard components, requires miscellaneous hardware & Crystal to complete. For Audio add the Audio subcarrier Kit, Order No EME158

Use the Optional 252MXPR2537A Helical filter between the EME44 & a M57716 PA Kits to reduce the Double sideband AM Bandwidth. Tuning this filter to the USB of the AM signal will reduce interference to other users of the 70cm band, along with increasing the efficiency of the Power Amplifier. This filter or a suitable interdigital filter, will be required for transmitting on 426 or 444.250MHz in all parts of Australia as per the current regulations to reduce the lower sideband.

2.4GHz MULTIPLIER KIT

The Multiplier is suitable for use as an ATV multipler to 2.4GHz, or local oscillator for transverter or receive converters. The multiplier can be used as either a 2X, 3X, or 4X multiplier for output within the 1850 to 2256MHz bandwidth of its 1/2 wave bandpass filters. The Multiplier uses 2 x ERA Amplifiers to produce up to +8dBm output.

The 1/2 Wave Tuned filter design of the EME139 is larger compared to other designs using trimmer capacitors & tuned PC board lines, but it requires no tuning & guarantees a clean local oscillator output with no test equipment required.

The single filter & Spur output is acceptable for most local oscillator applications for use with transverters & Receive Converters. For increased filtering for transmitter use EME139 KIT3 which includes an extra PCB as a second filter, & connect the two boards together back to back.

The EME65, 500MHz oscillator is suitable for driving the Multiplier. The complete Kit includes the PC board, & all onboard components. The Kit requires miscellaneous hardware to complete.

Specifications: Freq Range: 1960 – 2360MHz +/-3dB
Input: 4x 490 to 590MHz +3 dBm
Alternative Input: 2 x 980 to 1180MHz, 3x 653 to 787MHz +3dBm
Output: +3 to +8dBm Depends on Input frequency
Powersupply: +12volts 75mA

Use the EME139 KIT1 for a Local oscillator for 2400MHz Transverter or RX Converters. For extra Local Oscillator filtering, use the EME139 KIT3which includes an extra EME139 PCB for extra filtering. For 2400MHz ATV, use the EME139 KIT2 which replaces the ERA1 with an ERA5 for more output power. Please note that if you are going to use the EME128 2Watt Poweramplifier which requires < 5mW drive for ATV then use the EME139 KIT1. The EME139 PCB needs to be cut down in size on a bench grinder for 2400MHz use.
