Teledyne Microwave Solutions – Cougar Amplifier Series | Standard Amplifiers:
Teledyne RF & Microwave, a Business Unit of Teledyne Microwave Solutions (TMS), supplies catalog and custom RF and microwave amplifier designs for aerospace, defense, and industrial applications. These standard amplifiers, originally designed by Teledyne Cougar, provide both excellent stability and cascadability.
Amplifier Circuit Design:
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 -55°C to +85°C case temperatures. The nominal bias on the majority of the models is 15 volts, with many models biased 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 3rd order intercept performance when biased at 12-volts. Cougar's standard amplifiers use an ultra broadband circuit technique to extend the usable frequency limit down to 100 kHz on some models.
Microwave Amplifier Circuit Design:
Each Cougar microwave amplifier is designed using Lange couplers to give a balanced amplifier design covering the 6 to 20 GHz frequency range. The nominal bias on the majority of the models is 12 volts, while others are designed to operate in the 5- to 8-volt range. One, two, or three stage designs are available to address customer needs. Cougar's hermetic CougarPak™ is the standard package for microwave amplifiers.
