Cougar Components AC4064C

The Cougar Components AC4064C is a RF amplifier operating across the 800 MHz to 4000 MHz band, engineered in chip and wire hybrid construction for cascadable multi-stage applications. This TO-8 packaged device delivers 20.0 dB minimum small signal gain with excellent gain flatness of ±0.6 dB across 0–50° C, maintaining 19.0 dB gain over the extended -55 to +85° C temperature range. The AC4064C achieves a low noise figure of 3.0 dB (0–50° C), with power output at 1 dB compression rated at +16.0 dBm in standard conditions and +15.0 dBm extended temperature operation.
