Bangalore: Analog Devices (ADI), a provider of semiconductors for signal processing applications introducted its two new high-performance RF (radio frequency) passive mixers. These can be used for a variety of wireless applications, such as cellular base station receivers, transmit observation receivers and radio link down converters.
Designing for these applications requires high linearity and low noise and 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.
According to ADI, the new single-channel ADL5353 and dual-channel ADL5354 integrated passive mixers simplify designs, offer better performance and complement ADI's broad mixer portfolio by extending the frequency coverage of ADI's mixer products. Operating in the 2300 to 2900 MHz frequency range, ADI claims that the single-channel ADL5353 mixer and the dual-channel ADL5354 mixer 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 are available now. The ADL5353 single-channel mixer is available in a 20-lead LFCSP and is priced at $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 $9.98 per unit in 1,000-unit quantities.
