HMC639ST89ETR

HMC639ST89ETR is a GaAs pHEMT, high linearity, low noise, wideband gain block amplifier covering 0.2 to 4.0GHz. This 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 +22dBm 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. Applications include cellular / PCS / 3G, WiMAX, WiBro, & fixed wireless, CATV & cable modem, microwave radio, IF and RF sections.
