Description
The AP725 Series is a high performance line of SAW oscillators providing superior communication distances for
frequencies of 350 MHz to 4,000 MHz and phase lock loop for heritage applications. The radiation tolerant voltage
controlled SAW Oscillators (VCSO) are designed for space, satellite communications and aerospace systems.
The VCSOs deliver low phase noise performance (-109dBc/Hz at 1 kHz) and low vibration sensitivity (2 x10-9 per g). API’s
space-screened VCSOs are standard products that can be modified to customer requirements for output frequency,
frequency range and control voltage sensitivity.
API’s VCSOs meet exceptional radiation tolerance at testing levels with radiation exposure to 200 kRad total dosage. The
VCSOs are constructed in hermetically sealed metal packages using ruggedized hybrid construction to provide highreliability and outstanding performance over a wide temperature range (-55°C to +100°C). This series includes models
which have internal frequency multiplication of 2 or 4 to provide output frequencies in the 700 MHz to 4,000 MHz range.
