Power Amplifiers
-
Power amplifiers are designed and manufactured by utilizing the most advanced PHEMT or MMIC devices, thin film technologies, and an improved DC power supply to deliver a high output power with superior power added efficiency (PAE) and high linearity. While standard models focus on general purpose applications, additional models with differing frequency ranges, gains and power levels are listed on the website. Custom designs are also offered to meet any user’s specific needs.

Ultra Low Level DC Voltage Amplifiers
-
The EM A10 is a low level amplifier module for sensitive measurements, data collection and systems, where signals below 1 nanovolt may be measured. It is ideal for the input unit for precision voltage measuring systems, requiring voltage sensitivity for measuring low noise and low impedance sources. The noise level of the A10 is equivalent to a perfect resistor of about 20 ohms. When used with a digital voltmeter, steady one nanovolt digits may be displayed, with a response time constant of less than a second. The input voltage stability of the A10 is very high, with the drift around a nanovolt per degree C. The input connectors are made from pure copper. The input impedance is very high, and is time dependent, determined by the loop gain.

RF Amplifiers Bias Controllers
-
RF amplifier bias controllers generate a regulated drain voltage and actively adjusts the gate voltage of an external amplifier to achieve constant bias current. It can be used to bias any enhancement and depletion type amplifier operating in Class-A regime with drain voltages (VDRAIN) as specified. These devices achieve excellent bias stability over supply, temperature and process variations, and eliminates the required calibration procedures used to prevent RF performance degradation due to such variations.

The EDFA slot module of FOTS system with built-in power booster EDFA module offers a special function that is able to change the optical signal amplification feature variously, which is followed by user’s driving embedded pump LD freely. The output power of eash pump LD can be controlled separately by the program that is set up by user. When an optimum optical signal amplification particularity is needed, it is made up so that it can be materialized by choosing the Default mode provided along with User mode. More stable application of EDFA is possible through the monitoring of the factors such as in/out signal power, gain, alarm status and pump LD enabled by the application of FPGA processor which makes high speed driving possible. It is also set up that user’s present-time monitoring and control through LCD monitor of system main frame or GUI display for remote control can be possible. Through optimization of amplifier gain, noise figure, and saturated output power, this EDFA module will expand test capabilities in systems, components or sub-assembly manufacturing.
