LTC5566 300MHz to 6GHz Dual Programmable Gain Downconverting Mixer Fea T Descrip T n 12dB Power Conversion Gain The LTC 5566 dual programmable gain downconverting n 35dBm Output IP3 mixer is ideal for diversity and MIMO receivers that require n precise gain setting. Each channel incorporates an active 15.5dB Range IF DVGA in 0.5dB Steps n mixer and a digital IF VGA with 15.5dB gain control range. Programmable RF Input Tuning n The IF gain of each channel is programmed in 0.5dB steps Reduced Power Mode n through the SPI. 3.3V Single Supply n Simple SPI for Fast Development Programmable RF input tuning via the SPI or parallel n 40C to 105C Operation (T ) C control lines makes the device attractive for wideband n Very Small Solution Size radio applications. Furthermore, a reduced power mode n 32-Lead (5mm 5mm) QFN Package is available, programmed through the SPI. Integrated RF transformers provide single-ended 50 in- a T puts. The differential LO input is designed for single-ended or differential drive. The differential IF output simplifies n 4G and 5G MIMO Receivers the interface to differential IF filters and amplifiers. The n Diversity Receivers mixers are optimized for use up to 5GHz but may be used n Distributed Antenna Systems (DAS) up to 6GHz with degraded performance. n Network Test/Monitoring Equipment L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Software-Defined Radios Technology Corporation.
