InGaP Gain Blocks For Half A Buck?

A pair of gain blocks from Avago Technologies offer cost-effective solutions for boosting signal levels in WiMAX and satellite television products. Based on InGaP heterojunction-bipolar-transistor (HBT) technology, the monolithic-microwave-integrated-circuit (MMIC) AVT-51663 and AVT-53663 amplifiers are ideal for cellular infrastructure and other wireless applications from DC to 6 GHz. Model AVT-51663 typically provides 19-dB gain, +24-dBm third-order intercept point, and +12.5-dBm output power at 1-dB compression with 3.2-dB noise figure at 2 GHz, running from 37 mA and +5 VDC. Model AVT-53663 operates with +5 VDC and 48 mA for typically 19.5-dB gain, +5-dBm output third-order intercept point, +15-dBm output power at 1-dB compression, and 3.2-dB noise figure at 2 GHz. Both are internally matched to 50 Ohms and supplied in RoHS-compliant SOT-363 surface-mount packages. The models AVT-51663 and AVT-53663 gain blocks are available with prices starting at $0.31 and $0.33, respectively, in 10,000 volumes.
