A 60-finger class-A SiGe linear power amplifer (PA) w ith 22dBm of 1dB compress point output power (P 1dB),11dB of power gain (G p) and 26.1% of power added efficiency (PAE) @900MHz,3.5V/0.2A is demonstrated.
Finally, the scheme of the RF receiving/ transmitting system of the radar target simulator is presented based on the special requirements of a radar system. According to the scheme, we have accomplished the design and the realization of a mixer, a quadrature modulator/demodulator, a low noise amplifer, a high gain amplifer, a high frequency power amplifer and a frequency converter.
A new electron beam (EB) control system was developed in a general vacuum EB machine by equipping it with an industrial control computer, programmable logic control (PLC), deflection coil, data acquisition card, power amplifier, etc.
A Two-Channel Power Amplifier with a Diplexer Output
A Low-Consumption Ultrabroadband Power Amplifier with the Overload Protection
An ultrabroadband power amplifier with automatic control of the consumption current intended for operation into an unmatched load is described.
A power amplifier is described in which, in order to combine the powers of channel amplifiers, directional couplers are used that are based on helical transmission lines placed in a cylindrical shield.
