WebNote that the reference design incorporates a 900MHz BPF (approx. 0.6dB IL) at Tx output. Reference design and EV kit provide almost identical output power at the PA. Supply current for the reference design is less than 10mA higher than the EV kit at full power. This is due to the increased bias to the PA that decreases the VCO pulling.
