Enabling high-density radio cards by combining multiple discrete functional blocks into a single device, the ADRF6601/2/2/4 series of mixers and ADRF6701/2/3/4 series of modulators meet the demanding performance required by higher-capacity base stations. With this breakthrough level of integration, the company claims that base station manufacturers can realize an unprecedented 60% reduction in board space and a significant savings on bill-of-materials costs.
The four ADRF670x products integrate a high-dynamic-range analog I/Q modulator, RF output switch, and PLL with integrated VCO. The modulator input bandwidth of 500 MHz can support either a specified band or complex IF up-conversion transmit signal paths.
The four ADRF660x products integrate a high-linearity active RF mixer, RF input balun for single-ended 50-Ω input, and a PLL synthesizer with integrated VCO. The active mixer provides a voltage conversion gain of 6 dB, alleviating the need for additional IF amplification over competing passive mixers. The differential IF output is capable of supporting IF frequencies up to 500 MHz.
All eight devices share a common SPI control interface and are software compatible. (Ea/10,000: ADRF660x, $8.98; ADRF670x, $9.98 — samples available now.)
