Active Mixer Provides High Dynamic Range for Applications to 3.7 GHz

A new high linearity active downcon-verting RF mixer from Linear Technology can significantly reduce the cost and greatly sim-plify the design of 3G cel-lular basestations and other high performance wireless equipment. The LT5527 RF mixer features an operating frequency range extend-ing to 3.7 GHz. At 1.9 GHz, the LT5527 offers IIP3 (Input 3rd order Intercept Point) of 23.5 dBm, conversion gain of 2.3 dB, and a Noise Figure of 12.5 dB, meeting the dynamic range requirements of 3G cellular basestations and other high performance wireless infrastruc-ture receivers.
