HD155101BF

RF Single-chip Linear IC for GSM and EGSM Systems

ADE-207-256A (Z)

2nd Edition

September 1998

Description

The HD155101BF was developed for GSM and EGSM cellular systems, and integrates most of the

functions of a transceiver. The HD155101BF incorporates the bias circuit for a RF LNA, a 1st mixer, 1st-

IF amplifier, 2nd mixer, AGC amplifier and an IQ quadrature demodulator for the receiver, and an IQ

quadrature modulator and offset PLL for the transmitter. Also, on chip are the dividers for the 1st & 2nd

local oscillator signals and 90˚ phase splitter. Moreover the HD155101BF includes control circuits to

implement power saving modes. These functions can operate down to 2.7 V and are housed in a 48-pin

LQFP SMD package.

Hence the HD155101BF can form a small size transceiver handset for GSM and EGSM by adding a PLL

frequency synthesizer IC, a power amplifier and some external components. See page 7 “Configuration”.

The HD155101BF is fabricated using a 0.6 µm double-polysilicon Bi-CMOS process.
