BGU8823

BGU8823/A Dual channel low-noise high linearity amplifier with DSA and SPDT Rev. 7 — 24 January 2022 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 (5 mm x 5 mm x 0.72 mm) 44-pin leadless package. 2 Features and benefits Dual channel (diversity and main) highly integrated LNA + DSA Frequency band 2.3 GHz - 2.7 GHz Noise figure = 0.7 dB High linearity: IP3O = 36 dBm High input return loss >12 dB High output return loss > 12 dB Unconditionally stable up to 20 GHz Digital step attenuator with 31 dB range and 1 dB step High linearity SPDT, Pi(1dB) = 35 dBm, IP3i = 50 dBm Programmable via 3 wire or 4-wire SPI (Read/write) Small 44-terminal leadless package 5 mm × 5 mm × 0.72 mm ESD protec...
