NP Technologies Model NP-499-1 The NP-499-1 is a 100 watt CW, military booster amplifier system designed to operate over the frequency range of 30 MHz to 88 MHz with a gain of 13dB. The NP-499-1 operates from 22 to 30 VDC. This PA is designed to boost the output power of of military VHF transceivers. The amp incorporates automatic T/R switching with bypass switch. It utilizes RF power MOSFET devices that provide high gain, wide dynamic range and excellent ruggedness. Download complete datasheet |
