A 2.4 GHz Transceiver

A 2.4 GHz TransceiverRF Front-end for ISM-Band Digital Wireless Communications.pdf : This paper is a comprehensive presentation
of the design, implementation, and measured
performance of a 2.4 GHz transceiver
RF front-end for ISM-band digital wireless
communication. A dual frequency conversion
strategy is employed in this RF front-end
(2.4 - 2.47 GHz). The 1st and 2nd IFs are 280
MHz and 55 MHz, respectively. The TDD
duplexing method is adopted in this module,
controlled by T/R switch. A Class-A two-stage
power amplifier, a preamplifier, single-ended
resistive mixer and low noise amplifier are
designed and combined with suitable IF RFICs,
filters and switches to form a transceiver RF
front-end (not including frequency synthesizer).
The transceiver RF front-end has 22 dBm transmitting
power, with 15 dB conversion gain and 9
dB noise figure for receiving.
