0.1 GHz to 20.0 GHz - Flatpack
Low noise amplifiers (LNAs) are, by design and application, small signal amplifiers, intended to be the primary signal booster in RF subsystems; especially those where link-margins are critical.

Since overall LNA performance is determined largely by the first stage of amplification, CTT has combined its many years of experience in characterizing these devices with its expertise in the design of matching circuits to optimize noise figure performance.

CTT has developed an extensive "Library" of device parameters and compatible matching solutions, which allow predictable, repeatable noise performance. This "Library" is the basis for CTT's automated module production capability, which has been able to virtually triple module production efficiency.

These amplifiers use the industrial standard "flatpack" which has from 0.66 to 0.86 inches in width and 0.22 inches in height. A 0.1" mounting plate can be added to reach 0.32" thick. Each comes with removable SMA connectors.

This series of amplifiers utilize CTT's latest high gain, low noise modules. These MIC thin-film modules are eutechtically attached to metal carriers and mechanically mounted to the aluminum housings. This approach provides for maximum efficiency and durability. The design can be used in a wide range of environments and system applications. The units are designed to meet MIL-STD-883. The specifications shown below are guaranteed at +25°C case temperature, but the units can operate from -54°C to +85°C with degraded performance.

All units are screened to CTT's standard screening which includes visual inspection, burn in, temperature cycle, high temperature bake, leak test, constant acceleration, electrical test and final inspection. They are ideally suited for commercial, industrial and military applications, which require high performance, reliability, quick delivery and low cost.

Low-Noise Amplifier Comments (Apply to all AM, AF and AL Series amplifiers):
1. All specifications are guaranteed at +25°C CASEtemperature as measured in the linear region.
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 +85°C.
5. All units contain internal voltage regulators which can operate from +12 to +15 VDC.
6. Proper heat sink is needed to keep the case temperature below +105°C. Otherwise, permanent damage or degradation may occur.
7. Consult the factory for additional gain, power, higher frequencies, temperature compensation or any special functions.
8. Commercial versions are available with reduced screening and industrial grade FETs.
9. Maximum power without damage is +12 dBm min. Up to +20 dBm option available, contact factory.
10. For selected applications, lower noise-figures are available, contact the factory.
