The HD155101BF is an RF single-chip linear IC developed for GSM and EGSM cellular systems. It integrates most of the functions of a transceiver, including the bias circuit for an RF LNA, a 1st mixer, 1st-IF amplifier, 2nd mixer, AGC amplifier, IQ quadrature demodulator for the receiver, and an IQ quadrature modulator and offset PLL for the transmitter. It also includes on-chip dividers for the 1st and 2nd local oscillator signals and a 90° phase splitter, as well as control circuits for power saving modes. The HD155101BF can operate down to 2.7V and is housed in a 48-pin LQFP SMD package. By adding a PLL frequency synthesizer IC, a power amplifier, and some external components, the HD155101BF can be used to create a small-sized transceiver handset for GSM and EGSM. The HD155101BF is fabricated using a 0.6µm double-polysilicon Bi-CMOS process.
