Description

6 meter High Selectivity Low Loss Band Pass Filter 50 MHz – 54 MHz with PGA-103+ LNA and 1500 W QRO Transmit Receive Relays EME2-50N

Extreme high power device you always asked for. Has just two connectors so you don’t need to have split RX connector and revamped transceiver.

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

EME 2-50N device consists of three components:

 

1. 50 – 51 MHz High Selectivity, High Q, Low Loss RX Bandpass Filter BPF (up to 54 MHz).
2. Wideband Low Noise Amplifier.
3. High Power Relays with “N” connectors.

A “Bias-Tee” also known as a “DC Inserter” is a simple way to feed DC power through coaxial cable to the remote device such as a pre-amplifier and – or transmit/receive relays via the coaxial cable. The main task is to inject DC into or extract DC current from the coaxial cable, leaving the RF signal undisturbed. A bias tee is a passive RF circuit...
