Features

+ Guaranteed performance at 2.7 V power supply + Output power of 3 dBm into 50 Ω load (singleended) with 3 V operation + Direct RF modulation with or without offset mixer + Automatic power control (APC) capability + Accurate 90° phase shifter for carrier + Double-balanced active mixers minimize carrier feedthrough (origin offset) + Low-current sleep mode modulation of an RF carrier by I & Q baseband inputs. It is particularly suited for use in mobile and handheld cellular telephones designed to.
