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, 1stIF 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.

Features
• Highly integrated RF processing for hand-portables

    TX:
        - RF: 880 to 915 MHz
        - IF: 156 to 360 MHz
• Offset PLL architecture reduces TX spurious
• Low current consumption (Vcc = 3 V)
    RX mode: 42.5 mA Typ (including IFVCO current (2.5 mA Typ)) + LNA transistor current (5.6 mA Typ)
    TX mode: 38.0 mA Typ (including IFVCO current (2.5 mA Typ)) Idle mode: 1 µA Typ
• Operating supply voltage:
    - Phase comparator and TX VCO driver circuits: 2.7 to 5.25 V
    - Other blocks: 2.7 to 3.6 V
• Operating temperature range: –20 to +85°C
• 48 pin SMD Low Profile Quad Flat Package (LQFP): FP-48
