A Complete Solution for 430-450 MHz 1200 W Transmit-Receive 70 cm Competitions and Moon Bounce EME2-432
QRO – Extreme power on transmit and low noise on receive with integrated Input band-pass filter.
With two connectors doesn’t need to split and receive a separate connector.
EME2-432 device consists of three components:
1. 70 cm 430 – 440 MHz Ultimate Receiving Bandpass Filter on the input side.
2. Wideband Low Noise Amplifier.
3. High Power High Current Relays + isolation relays.
4. By order, the Fail Safe Relay option
5. By order, integrated super high selectivity SAW filter with a bandwidth of just about 8 MHz. From 430-438 MHz
