LOW PHASE NOISE VCOs

API Technologies' Voltage Controlled Oscillators (VCOs) are high quality frequency generation devices designed to serve both commercial and military requirements. Using high performance varactor diodes and optimizing circuit design techniques, API Technologies achieves superior high selectivity performance.

Gold Substrates
Low Junction Temperatures
Added Temperature Stability
High Output Power
Lowpass Filtering

We use thermistors on all VCO designs
for added temperature stability.

Gold substrate film yields lower loss
and enhances phase noise performance.

Ceramic and metal construction provides
low junction temperatures.

We use bipolar transistors to achieve low phase noise and high output power.

We integrate a unique low pass filter
for superior harmonic performance.

Screening to MIL-STD-883B is available.

Rugged construction for
demanding environmental applications.
