Packaged Broadband Millimeter-wave Amplifiers
The models AB028H1-14 and AB038H1-14 high gain amplifiers are designed for 23 to 30 GHz and 36 to 41 GHz, respectively. The AB028H1-14 features 36 dB of gain, +16 dBm of output power and 3 dB of noise figure. The AB038H1-14 offers 30 dB of gain, +16 dBm of output power and 4 dB of noise figure. Both amplifiers operate from a single voltage supply, thereby simplifying bias requirements. The series also includes variable-gain amplifiers (AB028V1-14) and low noise amplifiers (AA028N1-99 and AA038N1-99). Price (AA028N1-99): $30.98 (10,000).

Broadband RF Amplifier
The model 150A400 broadband RF amplifier is designed for laboratory applications that require instant bandwidth, high gain and moderate output power. The 100 kHz to 400 MHz amplifier is well suited for bulk current injection applications for conducted immunity in the automotive industry as well as antennas and component immunity testing and wattmeter testing. Its load tolerance makes it ideal for harsh test environments where SWR exceeds 6.0. The amplifier also features a digital control panel with built-in IEEE and RS-232 interface. When used with an RF sweep generator, the amplifier provides 150 W of swept power (min). Push-pull MOSFET circuitry lowers distortion, improves stability and allows operation into any load impedance without damage. Price: $16,000.

869 - 894 MHz Power Modules
The 200 W QuikPAC™ power modules for the 869 to 894 MHz band enable the development of very high power amplifiers by reducing the number of individual stages that must be combined to achieve power levels in excess of 400 W. The power modules solve the problem of matching to the very low impedance of high power transistors with the combination of a new, specially designed XeMOS MOSFET transistor and innovative impedance matching circuits. Other features of the QuikPAC power modules include single-polarity operation, 50 W RF interfaces, high gain and low intermodulation distortion.
