BGU8822
description
The BGU8822/A, also known as the BTS5201M/A, is a highly integrated dual channel digitally controlled low noise amplifier (LNA) with digital step attenuator (DSA) and a single-pole double-through (SPDT) switch. The BGU8822/A supports receivers (main and diversity) in both TDD and FDD systems. It has a first stage LNA optimized for sensitivity, followed by a DSA and output stage amplifier. To support highly integrated solutions and reduce platform costs a standalone SPDT switch is included.
The <keyword keyref="btn"/> is optimized for frequency band 1.4 GHz
- 2.2 GHz, but supports 2.2 GHz
- 2.7 GHz as well.
The <keyword keyref="btn"/> is controlled via SPI bus, supporting both 3- and 4-wire configurations. Additionally, in TDD systems the LNAs and DSA can also be controlled via direct-access pins.
The <keyword keyref="btn"/> is housed in a small footprint (5 x 5 x 0.72 mm) 44-pin leadless package.
