RF133
RF/IF Transceiver For GSM Applications
The RF133 RF/IF Transceiver is a highly integrated, monolithic device optimzed
for use in GSMand other TDMA single-band or multi-band applications.
The receive path of the device consists of three Intermediate Frequency (IF)
amplifiers with selectable gain, an I/Q demodulator, baseband filters, DC offset
compensation circuitry, and selectable gain baseband amplifiers.
The transmt path of the device consists of an I/Q modulator and a frequency
translation loop designed to performfrequency up-conversion with high output
spectral purity. The translation loop consists of a phase/frequency detector, a
charge-pump, a mxer, and buffers for the required isolation between the RF input,
Local Oscillator (LO), and IF inputs.
The device package and pin configuration are shown in Figure 1. A block diagram
of the RF133 is shown in Figure 2. The signal pin assignments and functional pin
descriptions are found in Table 1.
