GaAs amplifier IC works from 6GHz to 14GHz

Made using heterojunction bipolar transistors, phase noise is -172dBc/Hz at 10kHz offset and it typically provides 12dB of signal gain and +30dBm output third-order intercept, according to component distributor Richardson RFPD which has the part and can provide design support for it.

Inputs and output are internally matched to 50Ω, easing integration into multichip modules.

The amplifier requires 74mA from a 5V collector supply.

According to ADI, the choice of L1 and C4 (see circuit above) are critical to obtain data sheet performance. In this case, L1 is a 56nH Coilcraft 0402DF-560XJR and C4 is a 0.1μF American Technical Ceramics 531Z104KTR16T. “Power the ADL8150 from a well regulated ultra-low noise
source,” the company advises. “LT3045EDD#PBF low-noise, high-PSRR [power supply ripple rejection] linear regulator is recommended.”

All of these components are included in an evaluation kit (ADL8150-EVALZ) – a four-layer PCB fabricated from Rogers 4350B and Isola 370HR. Its input and output ports have 2.9mm female coaxial connectors and 50Ω characteristic impedance. The components are rated for operation over the -40 to +85°C operating temperature range of the ADL8150.

Applications are foreseen in military, space, test, instrumentation and communications.
