Wide bandwidth and high efficiency are not the only features offered in our full line of higher power amplifiers. API Technologies also incorporates many features in their line of Smart Power Amps not normally found in power amplifiers.

Push-Pull Design Techniques, coupled with transistors that have been selected for high linearity characteristics, enable API Engineers to achieve this incredible performance including IP2 values of +120 dBm.

Better phase noise is a performance requirement often sought in today’s most advanced systems. API Technologies achieves guaranteed ultra low phase noise performance in its amplifiers using a combination of design techniques, material selection, and in-house testing.

When your amplifier requirements are for 100 units or more, we offer cost effective package options that combine savings and high performance in one product.

API offers a complete line of Filtered GPS Low Noise Amplifiers, which are ideal for applications where higher reliability is critical. These filtered low noise amplifiers are designed to reduce out-of-band interference while achieving high dynamic range.

API’s line of AGC Amps allows the user to anticipate receiver power levels and automatically adjust the output power to a desired level. With optional gain stages from 25 to 40 dB, this modular family of Low Phase Noise AGC Amps can be used for multiple applications from 50 MHz to 2000 MHz.

API utilizes advanced RF & Microwave linear and non-linear simulation for rapid prototyping and a reduced design cycle. The Push-Pull Design Techniques, coupled with transistors that have been selected for high linearity characteristics, enable API Engineers to achieve this incredible performance including IP2 values of +120 dBm.

• Dual band power conditioning and control with field downloadable firmware to support active reconfiguration with built-in monitoring.
• Better phase noise is a performance requirement often sought in today’s most advanced systems.
• API Technologies achieves guaranteed ultra low phase noise performance in its amplifiers using a combination of design techniques, material selection, and in-house testing.

For high volume applications, we utilize 3-D modeling to offer cost effective packaging options that combine savings and high performance in one product.

API utilizes state-of-the-art thermal simulation and scanning tools when designing their high power amplifiers.

The better the IP3, the more notable the receiver’s ability to separate and discern several tones that are processed simultaneously inside the desired passband.

A perfectly designed Push-Pull Amplifier should cancel the internally generated products and maintain signal Quality.

Push-Pull techniques help cancel even harmonics as well as intermods and helps to improve even-order intermods products.

API Technologies can customize any High Linearity Amp to meet your unique set of specifications.

API Technologies designs include IP2 values better than 110 dBm.

API Technologies offers customer assurance through guaranteed phase noise performance. In addition, plots are provided.

Lower phase noise means improved spurious signal suppression, making our amplifiers ideal for even the most challenging systems and requirements.

Our amplifiers feature better phase noise performance which means a better signal to noise ratio. Both typical and guaranteed phase noise data are available.

By incorporating expert design techniques, careful material selection, and in-house testing in the development process, API Technologies can guarantee ultra low phase noise performance in its line of Series PM Amplifiers. An “enhanced” Agilent ES5500 system coupled with a modified IFR low noise synthesizer assists in making this possible.

Improved phase noise performance means improved sub-clutter visibility.

Higher volume packaged amplifiers can cut your costs by as much as 75%!

API Technologies offers a variety of package options for its amplifier line including our Higher Volume (non-hermetic), surface-mount package. This particular package option not only helps keep costs down, but on higher power requirements, the transistor is bonded right to the CuMo heat spreader for cooler operating temperatures.

We have frequencies available up to 4000 MHz. API Technologies can customize any Surface Mount amplifier to meet your unique set of specifications.

Our engineers utilize superior CuMo heatsink in our surface mount amplifiers which provides optimum thermal performance.

• The module includes a wide selection of pre-filtering configurations including L1, L1/L2, L5, and L1/L5.
• Each high-selectivity filter protects the front end of the receiver by filtering any intentional and non-intentional interferers.
• The filters are optimized to work with both C/A-code and P-Code.

Gain Options
