3.1.5. Power Amplifier

The Sky77325 [U804] is a quad-band GSM850/GSM900/DCS/PCS power amplifier module that
incorporates an indirect closed loop method of power control. The indirect closed loop is fully self-
contained and it does not require loop optimization. It can be driven directly from the DAC output in the
baseband circuit. On-board power control provides over 50 dB of control range with an analog voltage
input (Vramp).
Efficiency is 49% at GSM850 and 53% at GSM900, DCS, PCS1900.

3.1.6. 26 MHz Clock

The 26 MHz clock (X801) consists of a TCXO(Temperature Compensated Crystal Oscillator) which
oscillates at a frequency of 26 MHz. It is used within the Si4205 RF Main Chip, BB Analog chip-set
(IOTA), Digital chip-set(Calypso G2).
