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
