Warranty: 30 Days

This item is a tiny 225 - 400MHz power amplifier module, manufactured in the UK by Plessey. The plot below shows output power vs frequency for two input drive levels, 40dBm (10W) and 42dBm (16W). Outside of the range shown, power falls off quite steeply , and this amplifier is NOT suitable for the UK 70cm amateur radio band. Perhaps retune is possible, but we have not investigated this. It DOES however cover the region 2 (USA) 1.25m band at 220 - 225MHz. The power supply is 28V dc for the collectors,

Please note, the internal picture shown below is infact a LIBRARY picture. The amplifier offered for sale in this advert has NOT been opened up by us.
