Broadband RF amplifier

2 May 2012 Telecoms, Datacoms, Wireless, IoT

The AMF-4D-02002650-90-20P from Miteq is a rugged, single-bias broadband coaxial amplifier. It has over 25 dB of gain from 2 GHz to 26,5 GHz, in a housing that is only 25,4 mm long and 21 mm wide without the field replaceable 2,92 mm connectors.

Gain flatness is a maximum of ±2,5 dB, though typical is ±2,0 dB. The device has a maximum noise figure of 9 dB in the full band, though the typical value is near 6 dB. This amplifier operates from -40°C to +75°C of base temperature, has a P1dB minimum of +20 dBm, typical IP3 of +26 dBm, and a current draw of maximum 450 mA from a single +15 V d.c. supply.

Port VSWR is typically less than 2:1 for both input and output. The device’s metal body with a CuW base provides excellent thermal characteristics while an hermetic sealing option is available if required. With its built-in sequencing, regulation and reverse bias and over-temperature and over-current protection, only a single positive bias is required. Frequency options from as low as 100 MHz to as high as 40 GHz are available.
