Analog Devices 108370-1 MMIC DC-4GHz RF Evaluation Board HMC478ST89
This is a Brand New Analog Devices Hittite 108370-1 SiGe HBT MMIC DC-4GHz RF Amplifier Evaluation Board HMC478ST89 / 478ST89E
General Description
The HMC478ST89 & HMC478ST89E are SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifi ers covering DC to 4 GHz. Packaged in an industry standard SOT89, the amplifi er
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 output power. The HMC478ST89(E) offers 22 dB of gain with a +30 dBm output IP3 at 850 MHz while
requiring only 62mA from a single positive supply. The Darlington feedback pair used results in reduced sensitivity to normal process variations and excellent gain stability over temperature while requiring a
minimal number of external bias components.
Features:
P1dB Output Power: +18 dBm
Gain: 22 dB
Output IP3: +30 dBm
Cascadable 50 Ohm I/Os
Single Supply: +5V to +8V
Industry Standard SOT89 Package
Robust 1,000V ESD, Class 1C
Included in the HMC-DK001 Designer’s Kit
Typical Applications:
