DUAL 6850

EME2-144 Preamp, BPF and relay switching 1.5kW

2m Ultimate Transmit-Receive Relay Switches,BPF,VLNA EME2-144 1500W
 

A Complete Solution for 144-148 MHz 1500W Transmit-Receive 2m Competition and Moonbounce System with Low Loss Receive Band Pass Filter and Preamplifier EME2-144

QRO – Extreme power on transmit and low noise on receive with integrated Input band-pass filter. Has just two connectors so you don’t need split RX.

QRO made on low dielectric loss RT/duroid® 5880 Laminates (not on FR4 Important!). 

EME2-144 device consists of three components:
1. 144 – 148 MHz High Selectivity, High Q, Low Loss RX Bandpass Filter BPF
2. Wideband Low Noise Amplifier.
3. Double High Power Relays with 16A contacts.
