BT2577 Datasheet, PDF (1/4 Pages) List of Unclassifed Manufacturers – 2.4 GHZ RF TRANSCEIVER

OVERVIEW DATA SHEET: BT2577
2.4GHz RF TRANSCEIVER
Features
General Description
• 2.4GHz ISM Band RF Transceiver
The BT2577 is a high-performance transceiver for
• ETS 300 328
worldwide 2.4GHz ISM band applications. It includes
• Air Interface complies with FCC Part 15 Rules
on-chip features such as the LNA, Modulator / Demodu-
• Power Management for Minimizing Supply Current
• Power Supply 3.0V + 10%
• Power Control for TX tranmission
• Operating Temperature: -40°C to +85°C
Functions
• Receiver:
Low Noise Amplifier (LNA) w/ Gain Control
Image Reject RF Mixer
lator, RF VCO, image-rejection mixer and upconversion
mixer.
T _{The receiver section of the BT2577 contains a Low}
Noise Amplifier (LNA), a downconverter (image rejection
E _{mixer), IF AMP, Limiter, FM demodulator, data slicer,}
RSSI, and RF Voltage Control Oscillator (VCO). The
E _{receiver is designed to require a minimal number of}
external components and pin count for cost effective-
SH ^ness.

The transmitter section will share the same RF VCO with
the receiver, but also includes FSK modulator, upcon-
verter, and power amplifier. The transmitter also
requires minimal external components for reducing mass
production cost.
Since there is no IF or RF PLL included on the BT2577,
the design engineer can choose the most appropriate
RF-IF PLL to use based upon their unique system power
consumption, cost and performance requirements.
Keeping the PLL Synthesizer separate from the rest of
the RFIC Transceiver also makes it possible to accom-
plish lower noise, and higher peformance designs, due
to the improved isolation between the high and low fre-
quency synthesizer sections and the RX and TX signal
conversion chains.
