RFR6122

The RFR6122 device is the radioOne Zero Intermediate Frequency (ZIF) fully integrated receive RFIC. The device provides an integrated low-noise amplifier (LNA), a single mixer and baseband filtering to provide full RF-to-baseband downconversion for the CDMA cellular band. Included on the chip are an integrated UHF voltage-controlled oscillator (VCO) and a local oscillator (LO) generation block, which produce all the LO signals required for CDMA cellular frequency band of operation. The Rx phase locked loop (PLL) resides on the RFT6122 companion IC. Extension of standby time is achieved by selective circuit power-down, gain control and bias current.

These RFR6122 features, along with all of the radioOne chipset functionalities, are controlled by the QUALCOMM MSM via the serial bus interface (SBI). Package type is a 32-pin 5 mm x 5 mm Quad Flat No-Lead (QFN32).
