902-928 MHz Power AMP

Designed for extending the range of 900 MHz wireless radio devices, this amplifier is particularly effective when used with Direct Sequence or Frequency Hopping Spread Spectrum radio modems. The unit provides the transmit power amplification as well as receive signal gain. 

The built-in dynamic power sensor in the amplifiers adjusts the radio frequency (RF) power output level by reading the input signal power. This auto gain adjustment delivers the maximum output power at various input levels while keeping the distortion at a minimum.

Ideal to increase the range of low power devices such as wireless LAN cards, low power radio modems and to recover the cable losses in many installations.
