... 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 ...

... Probability Distribution Function implies that what is important for longer talk time is the efficiency of low or medium power range rather than the efficiency at full power. WS1102 idle current and operating current at 16 dBm nominal condition. Average current calculated with CDMA PDF urban area and suburban area. This PA with low current consumption prolongs talk time by no less than 30 minutes compared to other PAs ...

... PCB Design Guidelines The recommended WS1102 PCB Land pattern is shown in Figure 14 and Figure 15. The substrate is coated with solder mask between the I/O and conductive paddle to protect the gold pads from short circuit that is caused by solder bleeding/bridging. Stencil Design Guidelines A properly designed solder screen or stencil is required to ensure optimum amount of solder paste is deposited onto the PCB pads ...
