T2801

DECT Single-Chip Transceiver

Description

The T2801 is an RF IC for low-power DECT appli-

cations. The HP-VFQFP-N48-packaged IC is a complete

transceiver including image rejection mixer, IF amplifier,

FM demodulator, baseband filter, RSSI, TX preamplifier,

power-ramping generator for power amplifiers, inte-

grated synthesizer, fully integrated VCO, TX filter and

modulation compensation circuit for advanced closed-

loop modulation concept. No mechanical tuning is

necessary in production.

Electrostatic sensitive device.

Observe precautions for handling.

Features

Supply-voltage range 3 V to 4.6 V (unregulated)

Auxiliary-voltage regulator on-chip

Low current consumption

Few low cost external components

No mechanical tuning required

Non-blindslot and blindslot operation

Unlimited multislot operation with advanced closed-

loop modulation

Supports multiple reference clocks (10.368 MHz/

13.824 MHz/ 20.736 MHz)

TX preamplifier with 0 dBm output power at 1.9 GHz

and ramp-signal generator for SiGe power amplifier
