HMC287MS8 v01.0701 MICROWAVE CORPORATION GaAs MMIC LOW NOISE AMPLIFIER with AGC, 2.3 - 2.5 GHz AMPLIFIERS - SMT 8 Typical Applications Features LNA for Spread Spectrum Applications: Gain: 21 dB • BLUETOOTH Noise Figure: 2.5 dB • HomeRF Gain Adjustment: 30 dB • 802.11 WLAN Single Positive Supply: +3V • 2.5 GHz Radios No External Components Ultra Small Package: MSOP8G Functional Diagram General Description The HMC287MS8 is a low cost Low Noise Amplifier (LNA) offering 21 dB of gain and a 2.5 dB noise figure from a single positive +3V supply that requires only 9 mA. The HMC287MS8G can be used as a variable gain LNA, offering 30 dB of gain control, which is controlled with a 0 to 3V analog voltage. The typical output 1dB compression point is +3 dBm and OIP3 is +7 dBm when in the maximum gain state. The compact LNA design utilizes onchip matching for repeatable gain and noise figure performance and eliminates the need for external matching circuitry to reduce the overall size of the LNA function.
