Rotary Joints

API Rotary Joints are not only designed for high speed operation and long life, but are known in the industry for low loss and durability. Integrating SAGE Labs and their team of engineers, API is now the source for both standard low loss and custom Rotary Joint requirements.

Delay Lines

API designs and develops a variety of Delay Lines which include: BAW, Coaxial, LC, Steel Dispersive, SAW Dispersive, and SAW Non-Dispersive.

Operational Amps

From Power Operational Amplifiers for use in power supply and motor driver applications, to Current Amplifiers for use as a buffer, or Fast Buffer Amplifiers excellent for use as line drivers, API designs feature rich OpAmps to meet your needs.

A/D and D/A Converters

API offers a selection of D/A and A/D Converters that deliver exceptional performance and high reliability.  Offering both CMOS and TTL compatible formats, these high efficiency DACs frequently run off +5 or +15 volts, provide stability over temperature ranges, and are laser-trimmed for high linearity performance.

PIN Diode Drivers

API offers a complete line-up of PIN Diode Switch Drivers with output current capability of 10 mA to 50 mA and switching speeds as fast as 6 ns. Thin film metalization on ceramic substrates ensures low parasitic capacitance for fast switching, small size, and excellent reliability.


API produces premier temperature compensated detectors.  Analog/Level Detectors convert a range of RF input powers to a corresponding DC output voltage level. Threshold Detectors output a TTL compatible signal when the RF level exceeds the preset threshold.


API’s Attenuator products are offered in both Digital and Voltage Variable configurations.  Digital Attenuators are available in frequency ranges from 10 to 2000 MHz. Voltage Variable Attenuators (VVAs) are available in frequency ranges from 5 to 2000 MHz when voltage variable gain control is required.


API offers receiver protection for frequencies from 5 MHz to 1000 MHz. With input power levels up to +26 dBm, use as a clean-up limiter with higher power limiters or stand-alone for lower power requirements.


Designing switches that exceeds customer expectations is paramount to building strong supplier relationships. That’s why API selectively employs double ball bonds on critical connections for added integrity and runs hybrids over temperature as part of the final test procedure.


API’s RF Mixer product line covers frequency ranges from 0.5 MHz to 26.5 GHz. Available in many industry standard surface mount, drop-in and connectorized housings, these RF Mixers are ideal for high reliability applications.
