Peripheral Circuit in Handset
Figure 10. Peripheral circuit.
Notes:
1. Recommended voltage for Vref is 2.85V.
2. Place C1 near to Vref pin.
3. Place C3 and C4 close to pin 1 (Vcc1) and pin 8 (Vcc2). These capacitors can affect the RF performance.
4. Use 50Ω transmission line between PAM and Duplexer and make it as short as possible to reduce conduction loss.
5. π-type circuit topology is good to use for matching circuit between PA and Duplexer.
6. Pull-up resistor (R1) should be used to limit current drain. 6.2 kΩ is recommended for WS1102.
