Low Cost VCO Provides Wideband Solution for Satellite Communication Systems
Z-Communications, Inc. (Poway, CA) is once again displaying its engineering prowess in VCO technology by
SMV5550B-LF. This high
performance VCO generates frequencies between 5000 and 6000 MHz, covering the 1000 MHz bandwidth within 0 to 10 V
of control. Even though the device covers a broad spectrum of bandwidth, the
SMV5550B-LF comes in a compact
package covering an area less than .10 sq. inches while exhibiting remarkably good phase noise performance of -80
dBc/Hz, typically, at 10kHz from the carrier.
SMV5550B-LF delivers 3 ± 3 dBm
into a 50 Ω load with a nominal 5 V supply and drawing typically 24 mA. In addition to its low noise performance,
this device also exhibits excellent second harmonic suppression of -35 dBc, typically, and provides better than
1.1:1 tuning linearity making it the ideal component for satellite communication systems. Load pulling is
furthermore minimized to less than 10 MHz with a return loss of 20 dB in any phase while it pushes less than 20
MHz/V with a 5% change in the nominal supply. A truly spectacular accomplishment by Z-COMM engineers once again!
This low cost performer operates at a temperature range of -40 to 85 degrees Celsius and is packaged in
Z-Communications miniature SUB-L surface mount package measuring a mere 0.3" x 0.3" x 0.08". For further
