HTC CONFIDENTIAL 3 宏達國際股份有限公司 High Tech Computer, Corp. coaxial type with switching function. In normal mode when the plug is not connected, RF circuit is connecting with the external antenna. In test mode, when the plug of an RF cable is connected, the RF circuit is connecting with the RF cable. The other RF connector is for the GPS function. RF circuits RF circuit consists of an RF transmitter, two power amplifier modules, an RF receiver, one diplexer, two duplexers. RF transmit IC The transmit IC includes an IQ modulator, LO generation and Distribution, one PLL circuit for generating TX LO, TX VCO circuit and other various control circuits. Transmit IC receives analog inputs and control signals from baseband chips and outputs RF signals to power amplifiers. Power amplifier modules Power amplifier module is used to amplify the RF signal from RF transmit IC to a suitable level meeting CDMA specifications. RF receive IC RF receive IC includes dual LNAs for Cellular and PCS bands, Rx LO generation and Distribution, low pass filter, on-chip VCOs for CDMA Rx and GPS, and control circuits. RF receive IC gets signals from the diplexer and duplexers, amplifies signals, and down-converts signals to output to baseband chip. RF diplexer and duplexers RF diplexer is used to split Cellular signals and PCS signals. Two duplexers are used for Cellular band and PCS band respectively. The duplexer is used to allow a transmitter operating on one frequency and a receiver operating on a different frequency to share one common antenna with a minimum of interaction and degradation of the different RF signals.
