Low-Cost VCO Seeks Wireless LAN Systems

Engineered for quick and easy integration into PLLs, the new SMV5300L voltage controlled oscillator is targeted at demanding wireless LAN applications. It generates frequencies between 5,220 and 5,420 MHz within a control voltage range of 0.5 to 4.5 Vdc, with error voltage taken directly from the IC’s charge pump circuitry. Although covering a broad bandwidth, the device is able to achieve a spectral purity of -81 dBc/Hz, typical, at 10 kHz from the carrier. The device suppresses the second harmonic to -30 dBc and draws just 26 mA of current from a 5 Vdc supply while providing 3±3 dBm of output power into 50W load. A surface-mount device, the SMV5300L measures 0.3" x 0.3" x 0.08" and is specified to operate over the extended commercial temperature range of -30°C to +75°C. Pricing is $15.95 each.
