LMH6522SQE/NOPB TI Dual DVGA | 54-WQFN (10x5.5) | 2.5GHz BW, 25dB Gain

Product Overview

The LMH6522SQE/NOPB from Texas Instruments is a high-performance dual-channel digital variable gain amplifier (DVGA) designed for wideband receiver applications. It operates over a frequency range from DC to 2.5 GHz, providing a gain range of -5 dB to +25 dB with 0.25 dB step resolution. The device features a 3-wire SPI interface for gain control and includes an integrated power detector. Housed in a compact 54-pin WQFN package (10x5.5 mm), it is ideal for space-constrained designs.
