Avago launches high-linearity broadband InGaP HBT gain blocks

Avago Technologies has launched the AVT-55689 and AVT-54689 high-linearity gain block amplifiers, featuring low current consumption and robust electrostatic discharge (ESD) protection and housed in an industry-standard SOT-89 package.

Ease of use and extended broadband performance (operating in frequency bands from DC to 6000MHz) suit cellular and WiMAX wireless base-stations, satellite and cable TV set-top boxes, military equipment, and a variety of other wireless applications, says Avago.

The gain blocks use indium gallium phosphate (InGaP) hetero-junction bipolar transistor (HBT) process technology to achieve high reliability, temperature stability and performance consistency the firm adds.

At the typical operating condition of 5V and 83mA, the AVT-55689 delivers 17.2dB gain, 33.0dBm output third-order intercept point (OIP3), 19.4dBm output power at 1dB gain compression (P1dB) and 4.4 dB noise figure at 2000MHz.

At the typical operating condition of 5V and 60mA, the AVT-54689 delivers 17.4dB gain, 30.0dBm OIP3, 17.7dBm P1dB and 4.0dB noise figure at 2000MHz.

The devices are each internally matched to 50 ohms, eliminating the need for additional RF matching components. The cost-efficient devices’ broadband gain also suits cellular infrastructure designs that require the same driver amplifier or gain block for different frequencies, says Avago.

The AVT-55689 and AVT-54689 are priced starting from $0.63 and $0.59, respectively, in 10,000 unit volumes.
