HMC639 High IP3, Low Noise Amplifier, 0.2 - 4.0 GHz

Product Details

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.
