Passive RF mixers with on-chip balun and IF amplifier

Analog Devices has introduced two new high-performance RF (radio frequency) passive mixers for wireless applications, such as cellular base station receivers, transmit observation receivers and radio link downconverters.

Operating in the 2300 to 2900 MHz frequency range, the single-channel ADL5353 mixer and the dual-channel ADL5354 mixer integrates RF balun, LO (local oscillator) switch for dual LO frequency applications, LO driver and an integrated IF (intermediate frequency) amplifier. The balun integration enables the RF signal to be driven single-ended. The integrated IF amplifier saves the board from using external amplifier.

Analog Devices says both the ADL5353 and ADL5354 provide best-in-class IP3 and noise figure performance resulting in excellent spurious free dynamic range. These mixers also offer excellent noise figure under blocker signal performance. High spurious-free dynamic range and low noise figure under blocker performance enable the mixer to be used in applications where the receiver is operating in the presence of large interfering signals. The 5-V (nominal) ADL5353 and ADL5354 can also be operated on a 3.3-V supply voltage for power-conscious applications.
