M/A-COM Technology Solutions Introduces New Wide-Band VHF Amplifier Modules

M/A-COM Technology Solutions introduced a new pair (10 watt and 40 watt) of wide-band VHF power amplifier modules. These modules shorten the final application design stage in mobile, portable and base station communication systems for microwave and RF applications.

The multi-modulation modules consist of a driver and an output stage with built-in amplitude equalization and feedback networks. The 10W and 40W values were chosen to represent the output power that was technically achievable over five octaves of performance, along with linearity and efficiency.

The MAPM-020512-010C00 (10W) device is a dual stage module with over 20dB gain. It also includes a sophisticated ALC control pin that can be used for signal modulation, tight gain flatness or temperature correction, or other similar applications. When the ALC input is used for AM modulation, an external envelop detector is used to sense the output envelop of the power amplifier and supply a feedback signal to the ALC loop to linearize modulation.

The MAPM-020512-040C00 (40W) is very similar to the MAPM-020512-010C00 dual stage module in both size and performance. The key difference is that it also includes a DC gate bias pin for the MOSFETs rather than an ALC control pin. The MAPM-020512-040C00 operates in a frequency range between 20 to 512 MHz. The supply voltage is 30v, input power 10W, output power 30W, bias current 3.0A.
