HMC287MS8 / 287MS8E v02.0605 LOW NOISE AMPLIFIERS - SMT 4 GaAs MMIC LOW NOISE AMPLIFIER with AGC, 2.3 - 2.5 GHz 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 & HMC287MS8E are low cost Low Noise Amplifiers (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 HMC287MS8 & HMC287MS8E can be used as variable gain LNAs, offering 30 dB of gain control, which is controlled with 0 to 3V analog voltages. The typical output 1 dB compression point is +3 dBm and OIP3 is +7 dBm when in the maximum gain state. The compact LNA design utilizes on-chip 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.
