SA1630 - IF quadrature transceiver

Datasheet Summary

Description

The SA1630 is a 70

400 MHz I/Q transceiver for wireless LAN.

The Receive Path contains a digitally gain controlled linear IF amplifier, a pair of quadrature down conversion mixers and a pair of baseband amplifiers.

Features

  • Low supply voltage operation of 2.7V for main chip and 2.9V for charge pump.
  • Digital gain control of 70 dB in steps of 2 dB.
  • Rx Baseband amplifiers are capable of driving 1kW ||15pF.
  • Rx Baseband o/p’s clamp symmetrically, above 1Vp.
  • p in order to prevent dc bias shift under overdrive conditions.
  • Low current consumption: 33.5 mA in RX, 26.5 mA in TX, typical at 3V.
  • Package: LQFP.
  • 48, PCMCIA compatible.

INTEGRATED CIRCUITS SA1630 IF quadrature transceiver Product specification IC17 Data Handbook 1998 Jul 21 Philips Semiconductors Philips Semiconductors Product specification IF quadrature transceiver SA1630 DESCRIPTION The SA1630 is a 70–400 MHz I/Q transceiver for wireless LAN. The Receive Path contains a digitally gain controlled linear IF amplifier, a pair of quadrature down conversion mixers and a pair of baseband amplifiers. The transmit path contains a pair of quadrature up conversion mixers that transposes a quadrature baseband input signal up to IF frequency. An external VCO signal is divided internally and provides quadrature local oscillator signals for the mixers.
