Designed for wireless communications, the CRO2275A voltage-controlled oscillator (VCO) covers a 50-MHz bandwidth with an average tuning sensitivity of 15 MHz/V. Also, it covers 2250 to 2300 MHz in 0.5- to 4.5-V dc of tuning with a spectral signal of −85 and −114 dBc/Hz at 1- and 10-kHz offsets, respectively. It operates from 5 V at 20 mA and has output power of 1.5 dBm ±1.5 dBm into a 50-Ω load. Its operating temperature ranges from −10°C to 75°C. It suppresses the second harmonic to −10 dBc and pushes less than 1 MHz within 5% of the nominal supply voltage. And, it pulls less than 1 MHz with a 14-dB return loss for any phase. Price is $29.95.
