The device delivers 22dB of typical small-signal gain with a 2.5dB noise figure in the mid-band, providing the sensitivity and dynamic range required for microwave receiver front-ends. The output P1dB of +14dBm and output IP3 of +26dBm ensure that the amplifier can handle strong interferers without generating excessive distortion, critical for co-site and jamming environments. The RF input and output are internally matched to 50 ohms, requiring only external DC blocking capacitors and bias inductors for operation. The amplifier is powered from a single +5V supply drawing 80mA typical, with gate bias pins (VG, VG2) for adjusting the drain current and optimizing the noise figure versus linearity trade-off. The QFN-24 air-cavity package with LCP lid provides excellent RF performance and thermal characteristics.","working_principle":"The HMC564LC4TR uses a two-stage GaAs pHEMT amplifier topology. The first stage is optimized for low noise figure with a high-quality input match network that presents the optimal source impedance (Gamma-opt) to the gate of the first pHEMT device. The second stage is optimized for gain and linearity, providing the majority of the output power capability. Both stages share the +5V drain supply, with separate gate bias pins (VG for stage 1, VG2 for stage 2) that allow independent adjustment of the quiescent drain current. The gate bias voltages are typically set using resistive voltage dividers or active bias controllers. RF chokes on the drain bias lines isolate the RF signal from the power supply, while DC blocking capacitors on the RF input and output prevent the bias voltages from appearing on the external RF ports. The on-chip matching networks transform the device impedances to 50 ohms, eliminating the need for external matching components.","pin_description":"\n
