2. SGH-Z100 Circuit Description
1. SGH-Z100 RF Circuit Description
1. Antenna Switch Module (U100)
The antenna switch module allows multiple operating bands and modes to share the same antenna. A common antenna
connects to one of five paths: 1) UMTS-2100 Rx/Tx, 2) EGSM-900 Rx, 3) EGSM-900 Tx, 4) DCS-1800 Rx, and 5)
DCS-1800 Tx. UMTS operation requires simultaneous reception and transmission.
2. Filter
To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.
- GSM Rx FILTER (F100)→For filtering the frequency band between 925 ~ 960 MHz
- DCS Rx FILTER (F101)→For filtering the frequency band 1805 and 1880 MHz.
- WCDMA Rx FILTER (F203)→For filtering the frequency band 2110 and 2170 MHz.
- WCDMA Tx FILTER (F200)→For filtering the frequency band 1920 and 1980 MHz.
3. TCVCXO (OSC200)
To generate the 19.2MHz reference clock to drive the logic and RF.
4. Duplexer (F202)
A duplexer splits a single operating band into receive and transmit paths.
5. Isolator (MIS1)
An isolator between the Power Amplifier and the duplexer is highly recommended to provide constant load and source
impedances (respectively) to those devices.
6. UMTS PAM (U200)
This is a key component in the transmitter chain and must complement the RTR6200 IC precisely; jointly they dominate
the UMTS transmitter performance characteristics. Parameters such as gain, output power level, ACLR, harmonics, Rx-band
noise, and power supply current are critical.
7. GSM/DCS PAM (U102)
The PAM is a key component in any transmitter chain and must complement the rest of the transmitter precisely. For
GSM and DCS operation, the closed-loop transmit power control functions add even more requirements relative to the
UMTS PA. In addition to gain control and switching requirements, the usual RF parameters such as gain, output power
level, several output spectrum requirements, and power supply current are critical.
8. GSM/DCS Dual Tx VCO (OSC100)
The dual Tx VCO outputs, one for EGSM and one for DCS, drive a resistive network that splits the active signal into
two signals: 1) the input to the active PAM – this is the low loss path, and 2) the OPLL feedback signal.
9. Dual VCO (OSC201)
The dual-band UHF VCO is a key component within its phase-locked loop; VCO performance directly impacts PLL and
transceiver performance. GSM/DCS Rx/Tx LO & UMTS Rx LO signal is generated from this dual VCO's output.
