VCO for Base Station Equipment
Wed, 07/10/2002 - 7:12am
The V585ME28 VCO generates frequencies between 1200 and 2000 MHz, and covers the 800 MHz bandwidth within 1 to 20 V of control. Phase noise performances is 98 dBc/Hz typically, at 10 kHz from the carrier, making it ideal for base station test equipment. The V585ME28 delivers 8.25 ± 2.75 dBm into a 50 Ω load with a nominal 5 V supply and drawing less than 21 mA. The device exhibits second harmonic suppression of 13 dBc, typically. Load pulling is minimized to less than 18 Hz with a return loss of 14 dB in any phase while it pushes less than 5 MHz/V with a 5% change in the nominal supply. The device operates at a temperature range of 40 to 85°C and measures 0.5 inches × 0.5 inches × 0.13 inches.
