AMPLIFIER, 0.2 -4.0 GHz Functional Diagram General Description
The HMC639ST89(E) is a GaAs pHEMT, High
Linearity, Low Noise, Wideband Gain Block Amplifier
covering 0.2 to 4.0 GHz. Packaged in an industry
standard SOT89, the amplifier can be used as either
a cascadable 50 Ohm gain stage, a PA Pre-Driver,
a Low Noise Amplifier, or a Gain Block with up to
+22 dBm output power. This versatile Gain Block
Amplifier is powered from a single +5V supply and
requires no external matching components. The
internally matched topology permits this amplifier to
be readily ported between virtually any printed circuit
board material, regardless of its dielectric constant,
thickness, or composition. Electrical Specifications, Vs= 5V, TA = +25° C
