Description
W2020 highly integrated transceiver device included Lucent Technologies Microelectronics Group's hardware platform. been designed implement both EGSM standards. adding external LNA, power amplifier, filters, complete radio channel realized. W2020 transceiver been designed conjunction with CSP1088 (radio interface device) DSP1618 (digital signal processor) provide complete cellular solution. Figure shows block diagram W2020. consists transmitter, receiver, frequency synthesizers. W2020 transmitter includes offset oscillator mixer quadrature modulator with phase splitter. receiver includes mixer, digital gain controlled amplifier strip, quadrature demodulator. There three frequency synthesizers transceiver: frequency agile synthesizer used channel selection both transmit receive modes, fixed-frequency PLLs receiver transmitter. W2020 also includes logic control powerdown modes minimize supply current.

handportable phone. intermodulation condition that been considered includes those referenced recommendations handportable phone. Receiver Offset Calibration interface between W2020 device CSP1088 coupled. After signal received CSP1088, signal amplified before processing converter. Therefore, offset voltage W2020 outputs must canceled order maintain dynamic range receiver. calibration between performed CSP1088 device during time immediately prior receive burst. entire receive path W2020 device enabled except buffer. recommended that switched during calibration. This ensures that signal mixed into band while allowing mixer biased maintain constant impedance level filter input. This calibration procedure done prior each receive monitor burst since gain change each burst.

Transmitter
transmitter architecture direct-up modulator with frequency offset local oscillator. From input signals, offset mixer produces internal signal, which prevents external local oscillator from being pulled large transmitted signal. This configuration also improves carrier feedthrough remixing output signal which degrades adjacent channel leakage performance. phase shifter splits signal into with phase separation equal amplitude. signals in-phase quadrature-phase double-balanced mixers. resulting signals summed into output amplifier. order drive external bandpass filter prior power amplifier, preamplifier required.
Receiver
receive circuit designed meet blocking requirements without going into overload. case where signals greater than specification, overload indication provided. This overload indicator nonlatching detector. OVRLD output lead high when signal greater than trip point present specified time. When signal removed, output remains high same specified time. This avoids lockup minimizes amount lost data. also used some setting schemes. receiver uses single digital gain control along with quadrature demodulator. Accurate quadrature demodulation achieved using divide-byfour technique phase splitter. single allows inexpensive filter used with additional filtering requirements achieved baseband circuit (CSP1088). digital gain control gives high dynamic range resolution Additional required prior mixer very high input level antenna. receiver design carefully considered requirements blocking intermodulation. complete system analysis been undertaken order ensure performance without need expensive external components. connection filters either single-ended balanced techniques. blocking conditions that have been considered receiver design have been taken from 05.05 recommendation class
Frequency Synthesizers
There fixed-frequency local oscillators programmable oscillator. local oscillators (117 MHz) inductor/varactor tuning. oscillator (996 MHz-1032 MHz) uses microstrip inductor/varactor tuning. Standard phase-locked loop techniques employed synchronize oscillators stable references derived from master clock. Settling time start-up times loop filter components order maintain accuracy flexibility. frequency must programmed when W2020 switched from state other state.
Local Oscillators
Both local oscillators fixed divide-by-13 counter derive reference frequency (Figure frequency divided counter achieve reference frequency MHz. counters technology achieve division minimize spurious frequencies generated. phase detector digital type using D-type flip-flops compare frequency which then feeds current sources supplying external loop filter. oscillator referenced positive supply, oscillator referenced ground.
