Regulators
Most of the RF voltage regulation functions are located in the regulator IC
CCONT. It has 8 separate regulators with power on/off controls (see fig
2). Regulator VR6 is used only for the COBBA_D IC and the rest of the
regulators VR1–VR7 are reserved for the RF blocks. VR7_bias controls
the 800MHz PA bias to boost better efficiency in analog mode and at
power levels 6 to 10 in digital mode. V5V voltage is used for the PLL
charge pump supply. In dual band phone there is a need for 5 additional
regulators, which are integrated in Penta regulator IC.
Receiver
DAMPS800 RX
The receiver is a double conversion receiver. Most of the RX functions
are integrated in two ICs, namely receiver front end and EROTUS. Re-
ceiver front end contains a LNA and the 1st mixer. Analog and digital IF–
parts are integrated in the EROTUS.
