BGU8821/A

Dual channel low-noise high linearity amplifier with DSA and

SPDT

Rev. 6 — 15 April 2020

Product data sheet

1 General description

The BGU8821/A, also known as the BTS5201L/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 BGU8821/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 BGU8821/A is optimized for frequency band 700 MHz - 1000 MHz, but supports

452.5 MHz - 457.5 MHz as well.

The BGU8821/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 BGU8821/A is housed in a small footprint (5 mm x 5 mm x 0.72 mm) 44-pin leadless

package.
