Dual channel low-noise high linearity amplifier with DSA and
SPDT
Rev. 6 — 15 April 2020
Product data sheet
1 General description
The BGU8823/A, also known as the BTS5201H/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 BGU8823/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 BGU8823/A is optimized for frequency band 2.3 GHz - 2.7 GHz.
The BGU8823/A 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 BGU8823/A is housed in a small footprint (5x5x0.72 mm) 44-pin leadless package.
