Z-Communications introduces a VCO ideally suited for EDGE base stations. The V613ME05 generates frequencies between 2110 and 2170 MHz while exhibiting a silent signal. Realizing a spectral purity of -105 dBc/Hz, the V613ME05 is still able to attenuate the second harmonic to better than -30 dBc. It covers the bandwidth within a 0.5 to 4.5 V DC of control voltage with an average tuning sensitivity of 38 MHz/V. This device operates off of a 5 V DC supply while drawing 17 mA, offering the end user 0 ± 3 dBm of output power into a 50 W load. This device operates at a temperature range of -40°C to 85°C.
