Integrated RF mixers operate over 2300 to 2900MHz

Analog Devices, Inc. debuts highly integrated passive mixers, the ADL5353 and ADL5354 designed for applications requiring high linearity and low noise. Designing for such applications has always been a challenge as existing mixer solutions often require external components, such as baluns and matching components that add complexity to the design. ADI's new single-channel ADL5353 and dual-channel ADL5354 integrated passive mixers simplify designs, offer best-in-class performance, and complement ADI's broad mixer portfolio by extending the frequency coverEMSEMS_age of ADI's mixer products.

Targeted at a variety of wireless applications, such as cellular base station receivers, transmit observation receivers and radio link down-converters, the two mixers operate in the 2300 to 2900MHz frequency range. The mixers offer the highest level of integration including an 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 provides the necessary gain, thereby eliminating the need for an external gain stage. 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 5V (nominal) ADL5353 and ADL5354 can also be operated on a 3.3V supply voltage for power-conscious applications.

Both the ADL5353 and ADL5354 are available now. The ADL5353 single-channel mixer is available in a 20-lead LFCSP and is priced at Rs.322.32 ($6.98) per unit in 1,000-unit quantities. The ADL5354 dual channel mixer is available in a 36-lead LFCSP and is priced at Rs.460.85 ($9.98) per unit in 1,000-unit quantities. Both mixers are well-suited to work with ADI's integrated PLL/VCO synthesisers including the ADF4350, ADF4360-0, ADF4360-1 and ADF4360-2 as well as PLLs including the ADF4106 and ADF4153.
