UPC2758TRF/IF射频/中频RFID的射频混频器规格书PDF中文资料

DESCRIPTION

The µPC8112TB is a silicon monolithic integrated circuit designed as 1st frequency down-converter for cellular/cordless telephone receiver stage. This IC consists of mixer and local amplifier. The µPC8112TB features high impedance output of open collector. Similar ICs of the µPC2757TB and µPC2758TB feature low impedance output of emitter follower. These TB suffix ICs which are smaller package than conventional T suffix ICs contribute to reduce your system size.

FEATURES

• Excellent RF performance : IIP3 = –7 dBm@fRFin = 1.9 GHz (reference)

IM3 = –88 dBc@PRFin = –38 dBm, 1.9 GHz (reference)

• Similar conversion gain to µPC2757 and lower noise figure than µPC2758

• Minimized carrier leakage : RFIo = –80 dB@fRFin = 900 MHz (reference)

RFIo = –55 dB@fRFin = 1.9 GHz (reference)

• High linearity : PO (sat) = –2.5 dBm TYP.@fRFin = 900 MHz

PO (sat) = –3 dBm TYP.@fRFin = 1.9 GHz

• Low current consumption : ICC = 8.5 mA TYP.

• Supply voltage : VCC = 2.7 to 3.3 V

• High-density surface mounting : 6-pin super minimold package

APPLICATIONS

• 1.5 GHz to 1.9 GHz cellular/cordless telephone (PHS, DECT, PDC1.5G and so on)

• 800 MHz to 900 MHz cellular telephone (PDC800M and so on)
