SA2400A - Single Chip Transceiver for 2.45 Ghz ISM band

Description

The SA2400A is a fully integrated single IC RF transceiver designed for 2.45 GHz wireless LAN (WLAN) applications.

It is a direct conversion radio architecture that is fabricated on an advanced 30 GHz fT BiCMOS process.

Features

  • The block diagram of the SA2400A Direct Conversion transceiver is given in Figure 1. It consists of the following functional blocks:.
  • A 79 dB adjustable gain range direct conversion zero IF receiver with 3 µs (typical) Tx to Rx switching time, and comprising the following:.
  • Front-end LNA with two internal gain states.
  • A fast on-chip closed loop composite RF and IF AGC with zoomed analog RSSI output and 8 µs settling time.
  • Quadrature downconverters from 2.45 G.

INTEGRATED CIRCUITS SA2400A Single chip transceiver for 2.45 GHz ISM band Product data 2002 Nov 04 Philips Semiconductors Philips Semiconductors Product data Single chip transceiver for 2.45 GHz ISM band SA2400A 1. DESCRIPTION The SA2400A is a fully integrated single IC RF transceiver designed for 2.45 GHz wireless LAN (WLAN) applications. It is a direct conversion radio architecture that is fabricated on an advanced 30 GHz fT BiCMOS process. The SA2400A combines a receiver, transmitter, and LO generation into a single IC. The receiver consists of a low-noise amplifier, down-conversion mixers, fully integrated channel filters, and an Automatic Gain Control (AGC) with an on-chip closed loop. The transmitter contains power ramping, filters, up-conversion, and pre-drivers.
