Narrowband Amplifiers Up to 100 Watts High & Medium Power Amplifiers
Power Amplifiers are CTT's forte. Over the past 25 years, the preponderance of our research and development has been devoted to this product line. As a result, numerous proprietary, unique approaches to microwave power amplification have been incorporated in, both our narrow-band, and broad-band power amplifiers. For example, development in low-loss output stage power combiners allow CTT to deliver 80 Watt X-band amplifiers in volume.

In narrow band applications, CTT's ability to deliver 80 Watts at X-band and 100 Watts at C-band has allowed system designers to eliminate intermediate amplification stages; thus, improving overall system reliability as well as reducing cost.

CTT's most recent contribution to microwave power is focused on the automated production of power modules. This capital investment has improved individual productivity by a factor of 3, and resulted in the introduction of more than 90 new power amplifiers!

These power amplifiers are available in narrow band (APN, ASN), wide band (APW, ASW), Octave (APO, ASO), and multioctave band (APM, ASM). Covering from 0.5 to 18 GHz, the AP series are designed to operate as linear amplifiers. The AS series operate in the saturated mode to attain maximum output power. CW output powers range from 3W to 100W. Special pulsed amplifiers can be ordered with even higher output power. CTT's unique MIC modules are designed to obtain higher output power, better VSWR and wider bandwidth. These MIC thin-film modules are eutechtically attached to metal carriers and mechanically mounted to the aluminum housings. Many units now use GaN or GaAs power FETs for the final stages.

All units have built in regulator and/or sequential bias circuit for protection. The specifications shown below are guaranteed at +25°C case temperature.

These units are ideally suitable for commercial, industrial, and military applications, which need low maintenance, high performance, reliability and quick delivery. They are most suitable for TWT replacements, intermediate power amplifiers, driver amplifiers, transmitters, radar, EW, ESM, UAV, point-to-point, and data-link communications.

Power Amplifier Comments:
1. Proper heat sinking is needed to keep the CASE temperature below +70°C. Otherwise, permanent damage or degradation may occur.
2. CTT can provide replacements for many hard to find products including those formerly produced by Avantek, Watkins-Johnson and Celeritek.
3. Noise figure will rise 0.015 dB/°C typically as the temperature increases.
4. P1dB will drop approximately 1 dB from +25°C to +70°C.
5. All units contain internal voltage regulators.
6. TTL control, pulsed amplification, monitor, detector and DC-DC power supplies are optional.
7. Consult the factory for additional gain, power, frequencies, temperature compensation or any special functions.
8. SP = Special Enclosure. Please contact the factory for outline drawing.
9. * = Saturated power (All AS Series amplifiers).
