= 1960MHz (PCS band), P
IN
= -30dBm, input and output matching networks are
optimized for the frequency band of interest, all input/output ports terminated in 50
Ω, V

A
= +25°C, unless otherwise
noted.) (Note 2)
Note 2: Minimum and maximum limits are guaranteed by design and characterization, but not production tested.
Note 3: The part has been fully characterized at the specified frequency range. Operation outside of this range is possible but not
guaranteed.
Note 4: Specification excludes circuit board losses.
Note 5: Measured with two tones, f
IN1
= 1850MHz, f
IN2
= 1850.8MHz, P
IN
= -33dBm for each tone.
Note 6: Measured with two tones, f
IN1
= 945MHz, f
IN2
= 945.8MHz, P
IN
= -33dBm for each tone.
Note 7: Measured with two tones, f
