DESCRIPTION

The µPC8130TA and µPC8131TA are silicon monolithic integrated circuits designed as variable gain amplifier. Due to 800 MHz to 1.5 GHz operation, these ICs are suitable for RF transmitter AGC stage of digital cellular telephone. These ICs are lower distortion than conventional µPC8119T and µPC8120T so that –15 dBm input level can be applied. These ICs also available in two types of gain control so you can choose either IC in accordance with your system design. 3 V supply voltage and minimold package contribute to make your system lower voltage, decreased space and fewer components.

FEATURES

• Recommended operating frequency: f = 800 MHz to 1.5 GHz

• Low distortion : Padj ≤ –60 dBc MAX. @Pin = –15 dBm, ∆f = ±50 kHz, VCC = 3.0 V, TA = +25 °C

• Supply voltage : VCC = 2.7 to 3.3 V

• Low current consumption : ICC = 11 mA TYP. @VCC = 3.0 V

• Gain control voltage : VAGC = 0 to 2.4 V (recommended)

• Two types of gain control : µPC8130TA = VAGC up vs. Gain up (Reverse control)

µPC8131TA = VAGC up vs. Gain down (Forward control)

• AGC control can be constructed by external control circuit.

• High-density surface mounting : 6 pin minimold package

APPLICATION

• 800 MHz to 900 MHz or 1.5 GHz Digital cellular telephone (PDC800M, PDC1.5G and so on)
