Overview
The HMC740ST89E is an InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier produced by Analog Devices Inc. This amplifier operates over a frequency range of 0.05 to 3 GHz and is packaged in an industry-standard SOT89 package. It is designed to serve as a cascadable 50 Ohm RF or IF gain stage, as well as a PA or LO driver, with an output power of up to +18 dBm. The device offers 15 dB of gain and a +40 dBm output IP3 at 100 MHz, and it can operate directly from a +5V supply. The HMC740ST89E is known for its excellent gain and output power stability over temperature, requiring only a minimal number of external bias components.
