BGU8823 - Dual channel low-noise high linearity amplifier

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.

Features

  • 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/wri.

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.
