(1) Two output tones at 104 dBµV within operating range

(2) Two output tones at 108 dBµV within operating range

(3) When controlling external AGC the current load on AGCOUT should be minimised

(4) For maximum performance, capacitive load should be resonated with appropriate inductance at chosen IF

frequency.
