Peripheral Circuit in Handset
Figure 21. 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 10 (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 kohm is recommended for WS2512.
