- RFL6200 (U702)
The RFL6200 includes an LNA circuit optimized for UMTS-2100 operation. The LNA is separated from all other
receive functions contained within the RFR6200 receiver IC to improve mixer LO to RF isolation ? a critical
parameter in the Zero-IF architecture.
- RFR6200 (U703)
The RFR6200 provides the Zero-IF receiver signal path, from RF to analog baseband, for UMTS-2100
applications. The RFR6200 accepts its UMTS input signal from the handset RF front-end design. The UMTS input
is configured differentially to optimize second-order inter-modulation and common mode rejection performance, and
implements MSM-controlled gain adjustments to extend the receiver dynamic range.
- RTR6250 (U602)
The RTR6250 supports multi-band, multi-mode phones with two receiver signal paths and three transmitter signal
paths:
Receiver paths
- EGSM-900
- DCS-1800
- PCS-1900
Transmitter paths
- EGSM-900 (using OPLL technique)
- DCS-1800 (using OPLL technique)
- PCS-1900
- UMTS-2100
Numerous secondary functions are integrated on-chip as well:
