SA1638BE 产品描述

100%全新原装,真空包装,可提供样板零售

SA1638BE 产品简介

Low voltage IF I/Q transceiver
DESCRIPTION
The SA1638 is a combined Rx and Tx IF I/Q circuit. The receive
path contains an IF amplifier, a pair of quadrature down-mixers, and
a pair of baseband filters and amplifiers. A second pair of mixers in
the transmit path transposes a quadrature baseband input up to the
IF frequency. An external VCO signal is divided down internally and
buffered to provide quadrature local oscillator signals for the mixers.
A further divider chain, reference divider and phase detector are
provided to avoid the need for an external IF synthesizer. Rx or Tx
path or the entire circuit may be powered down by logic inputs.
On-board voltage regulators are provided to allow direct connection
to a battery supply.
FEATURES
• Direct supply: 3.3V to 7.5V
• Two DC regulators giving 3.0V output
• Low current consumption: 18mA for Rx or 22mA for Tx
• Input/output IF frequency from 70-400 MHz
• Internal IF PLL for synthesizing the local oscillator signal

• High performance on-board integrated receive filters with
bandwidth tunable between 50-850 kHz
• Switchable alternative bandwidth setting available to allow
channel bandwidth flexibility in operation
• Designed for a widely used I and Q baseband GSM interface
• Control registers power up in a default state
• Optional DC offset trim capability to <200mV
• Only a standard reference input frequency required, choice of 13,
26, 39 or 52MHz
• Fully compatible with SA1620 GSM RF front-end (see Figure 9)
APPLICATIONS
• IF circuitry for GSM 900MHz hand-held units
• IF circuitry for PCN (DCS1800) hand-held units
• Quadrature up and down mixer stage>
