range of 1 to 12 Vdc. This innovative<br />
VCO features a spectrally<br />
clean signal of -<strong>10</strong>6 dBc/Hz<br />
@ <strong>10</strong> kHz offset and a typical<br />
tuning sensitivity of 23 MHz/V.<br />
The CRO2500C-LF is designed<br />
to deliver 7±2 dBm of output<br />
power into a 50 ohm load while<br />
operating off a 8 V DC supply<br />
and drawing typically 28 mA<br />
of current.<br />
This high-performance VCO<br />
operates over the extended commercial<br />
temperature range of -40<br />
to 85 ºC.<br />
The CRO2500C-LF features<br />
typical second harmonic suppression<br />
of 15 dBc and comes<br />
in Z-Comm‘s standard, low<br />
profile MINI-16-SM package<br />
measuring 0.5 x 0.5 x 0.22 in.<br />
It is available in tape and reel<br />
packaging for production requirements<br />
making it ideal for automated<br />
surface mount assembly<br />
and reflow.<br />
The CRO2500C-LF is well suited<br />
for basestation equipment<br />
and satellite communication<br />
applications that require low<br />
phase noise performance.<br />

High-Linearity<br />
Low-Power<br />
Demodulator<br />
Offers Unparalleled<br />
Performance<br />
RFMW, Ltd. announced design<br />
and sales support for the ParkerVision<br />
PV5870 demodulator/modulator.<br />
The PV5870 is<br />
a direct conversion quadrature<br />
demodulator/modulator designed<br />
for communication systems<br />
requiring excellent linearity<br />
with the lowest possible power<br />
consumption. Drawing only<br />
23 mA from a 3 V supply, the<br />
PV5870 consumes 1/5 th to 1/<strong>10</strong> th<br />
the power of similar demodulators<br />
yet provides superior noise<br />
figure performance (a 6 dB<br />
improvement over the nearest<br />
competitor).<br />
As a demodulator operating from<br />
400 to 3600 MHz, the PV5870<br />
offers excellent amplitude and<br />
phase balance and very low DC<br />
offset. Intermodulation products<br />
IM2 and IM3 can be optimized<br />
through adjustment. RF, LO and<br />
baseband interfaces are fully<br />
differential. The baseband outputs<br />
of the device can interface<br />
directly to baseband amplifiers<br />
or low-pass filters. The Parker-<br />
Vision PV5870 is offered in a<br />
4 x 4 mm QFN package and is<br />
available from stock.<br />
