NOTES:
• Recommended voltage for Vref is 2.85 V.
• Place C1 near to Vref pin.
• Place C3 and C4 close to pin 1 (Vcc1) and pin 10 (Vcc2). These capacitors can affect the RF performance.
• Use 50
• -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. 6.2 k is recommended for WS2512-TR1G.
