5 x 5-mm AGC operates from 50 to 800 MHz

The HMC992LP5E IF automatic gain control (IF-AGC) solution combines a high performance analog voltage variable attenuator (VVA) core with a high speed power detector in a compact 5 x 5 mm plastic package. The part is ideal for AGC implementation in the 50 to 800 MHz frequency range in LTE/WiMAX/4G, microwave radio, VSAT, test equipment and sensor applications. It offers a wide gain control range from –10 to 38 dB.

Its unique VVA core also provides a consistent gain slope vs. control voltage; a characteristic which enables easier implementation of AGC loops and provides a uniform transient response over the entire attenuation range. The part differentiates itself from these traditional VVAs by providing a constant OIP3 of 40 dBm over the entire attenuation range. Housed in a RoHS compliant 5×5 mm QFN leadless package, the IF-AGC requires only dc blocking capacitors and resistors, and is specified for –40° to 85°C.($12.06 ea/10-99; EVAL01-HMC992LP5E evaluation board, $740.00 — available now)
