Notes:
- Recommended voltage for Vref is 2.85V
- Place C1 near to Vref pin.
- Place C3 and C4 close to pin 5 (Vcc1) and pin 6 (Vcc2). These capacitors can affect the RF performance
- Use 50
Ω transmission line between PAM and Duplexer and make it as short as possible to reduce conduction loss
-
π-type circuit topology is good to use for matching circuit between PA and Duplexer.
- Pull-up resistor(R1) should be used to limit current drain. 6.2k
Ω is recommended for ACPM-7821
