LNA is self-biased with a single positive supply
The ADL9005 from Analog Devices is a gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), pseudomorphic high electron mobility transistor (pHEMT), wideband, LNA that operates from 0.01 GHz to 26.5 GHz.
It is in stock at distributor Digi-Key Electronics,
The LNA provides a typical gain of 17.5 dB from 0.01 GHz to 14 GHz with a positive gain slope from 14 GHz to 20 GHz, a 13.5 dBm typical output power at 1 dB compression (OP1dB) from 0.01 GHz to 20 GHz, a 2.5 dB typical noise figure from 0.01 GHz to 14 GHz, and a typical output third-order intercept (OIP3) of 26 dBm from 0.01 GHz to 14 GHz, requiring only 80 mA from a 5 V supply voltage.
Saturated output power (PSAT) of up to 16 dBm enables the LNA to function as a local oscillator (LO) driver for many Analog Devices balanced, in-phase/quadrature (I/Q) or image rejection mixers.
The ADL9005 also features inputs and outputs (I/Os) that are internally matched to 50 Ω, making it ideal for surface-mounted technology (SMT)-based, high capacity microwave radio applications. The ADL9005 is housed in a RoHS compliant, 4 mm x 4 mm LFCSP.
The amplifier is self-biased with a single positive supply, eliminating the need and board space required for complex bias sequencing circuitry.
Applications include instrumentation typically spectrum analysers and network analysers and electronic warfare.
