Designed for LTE and 4G cellular base stations, ADRF660x Mixers and ADRF670x Modulators each combine multiple discrete functional blocks into single device. ADRF670x models integrate analog I/Q modulator with input bandwidth of 500 MHz, RF output switch, and PLL with VCO in one RFIC, while ADRF660x models integrate high-linearity active RF mixer, RF input balun for single-ended 50 <font face='Symbol'>W</font> input, and PLL synthesizer with integrated VCO. All share common SPI control interface.

Model LT5527 high linearity, active downconverting RF mixer simplifies design of 3G cellular basestations. At 1.9 GHz, unit offers IIP3 linearity of 23.5 dBm, conversion gain of 2.3 dB, and noise figure of 12.5 dB. Local oscillator and RF inputs operate single-ended and have built-in 50 ohm impedance, requiring few external matching components. Low-noise LO buffer allows operation at -3 dBm LO drive level, reducing need for external filtering.
