Each Cougar amplifier is designed for unconditional stability and excellent cascadability. Gain flatness is maintained to typically ±0.2 dB or better, which improves cascaded flatness. Each module has internal power supply decoupling to minimize power supply cross talk and fine-grain ripple. All DC biasing circuits use temperature compensating bias to reduce DC current drift to typically ±0.3% from –55ºC to +85ºC case temperatures. The nominal bias on the majority of the models is 15 volts, while others are designed to operate in the 5- to 8-volt range. In addition, most 15-volt models have options for internal wire bond changes that provide full output power capability and third order intercept performance when supplied with a 12-volt source. Cougar uses an ultra broadband circuit technique to extend the usable frequency limit down to 100 KHz on some models.

Cougar's individual circuit designs are flexible and designed for easy combining. For example, model AR2589 represents a method for cascading two stages of gain in a single TO-8B package, which provides +28.3 dBm output power and 20.5 dB gain over the 100 to 2500 MHz bandwidth. The model AS6043, also a two-stage unit, typically produces +15.5 dBm output power and 15 dB gain from 10 to 6000 MHz.
