Functional Diagram
General Description
The HMC480ST89 is an InGaP HBT Gain Block
MMIC SMT amplifier covering DC to 5 GHz and
packaged in an industry standard SOT89. The
amplifier can be used as a cascadable 50 Ohm
RF/IF gain stage as well as a LO or PA driver with
up to +20 dBm P1dB output power for cellular/3G,
FWA, CATV, microwave radio and test equipment
applications. The HMC480ST89 offers 19 dB of
gain with a +34 dBm output IP3 at 1 GHz while
requiring only 82 mA from a single positive sup-
ply. The HMC480ST89 InGaP gain block offers
excellent output IP3 and flat +19 to +20dBm output
power performance through 5 GHz compared to
equivalent SiGe based products.
