The Mini-Kits High Performance VHF 2M RX/TX masthead Pre-amplifier has been designed to be easy to construct, and is suitable for the 144-148MHz Amateur Band. The design uses a Mini-Circuits PGA-103 E-PHEMT amplifier that has a very high dynamic range and ultra low noise figure, and provides superior performance to Mos or GaAs FETs. The design incorporates VOX RF sensed changeover Relays for Trasnsceivers up to 100 Watts CW without using sequencing, or can handle up to 500 Watts PEP if sequencing is used. An on board bias tee ( DC power injector ), allows the pre-amplifier to be antenna mounted and powered via the coaxial cable. A Tuned input T type filter and output low pass filter provides high rejection of signals at 50 and 430MHz.

THIS KIT IS NOT FOR BEGINNERS AND REQUIRES VERY EXPERIENCED SOLDERING SKILLS

The Product picture shows a completed EME220-2M-Rev1.3 KIT1 product with Optional BNC connectors.

This product is ideal for use with the Icom Multimode UHF transceivers including the IC275, IC820 / 821, 910, IC9100, and IC9700 that have a PREAMP switch to supply +12vdc out of the antenna connector on RX mode. Transceivers without this function will require an external bias tee like the Mini-Kits EME168-2-70 to supply DC power up the coaxial cable. Refer to the application block diagram and the
EME220 Kit Webpage for more information

Please Note: Built products usually need to be constructed and can take up to 2 weeks to ship depending on work load, but are normally shipped in few days.
