    Filtronic PLC can now offer the Cerus range of high-power E-band amplifiers for remote commercial or defence telecommunications applications, including LEO and HAPS.

   The high power range is now available in single -, four -, and eight-way amplifier versions. All amplifiers combine their GaAs HEMT PA Mmics, and these Mmics are matched in performance and waveguide power combinations to maximize power output. 

      Four - and eight-way models offer integrated temperature sensors with analog outputs for precise monitoring of thermal characteristics, as well as control circuit options for features including gain control, mute control and alarms.

     The amplifier operates in 71-76ghz and 81-86ghz bands, with a transmission power control range of 10dB and a small signal gain of 24dB in general. It also provides excellent saturation power output levels up to +36dBm and higher, and provides 1dB gain compression points at +31dBm.

      At +29dBm output power, the typical output third-order intermodulation product is +39.5dBm. The high linearity of the amplifier enables it to support 256QAM modulation for high capacity transmission.

     With a size of only 40mm x 40mm x 47mm and a weight of only 160g, its low SWAP(size, weight and power) makes it ideal for airborne and HAPS applications.

     WR12 waveguide is used for input and output connection, and multi-pin connector is used for DC connection.
