Low Phase Noise Amplifier, 10 MHz to 6 GHz

The ADL8154 is a small form factor, low phase noise amplifier designed for instrumentation, radar, and telecommunications applications. The phase noise from 2 GHz to 5 GHz is −172 dBc/Hz at 1 dB compression (P1dB) and 10 kHz offset.

The ADL8154 operates from a single positive supply (VCC); its bias current (ICQ) is set by a resistor connected between the RBIAS pin and the VCC1 and VCC2 pins. The RF input and RF output are DC-coupled and matched to 50 Ω. A bias inductor is required on the RF output.

The typical gain and noise figure are 16.5 dB and 3.5 dB , respectively, from 2 GHz to 5 GHz. The typical output third-order intercept (OIP3) and output second-order intercept (OIP2) are 34.5 dBm and 53 dBm, respectively, from 2 GHz to 5 GHz. The nominal supply voltage is 5 V, and the supply current is 125 mA.

The ADL8154 is fabricated on gallium arsenide (GaAs), heterojunction bipolar transistor (HBT). The device is housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP and is specified for operation from −55°C to +125°C.
