Handheld medical devices including microwave amplifier unit at device handle

A system, comprising:

• a microwave signal generator;
• and
• a medical device, including:
• a handle assembly including a first plurality of electrical contacts disposed thereon;
• a microwave-signal-amplifying module including:
• a microwave amplifier unit disposed within the handle assembly adapted to amplify a high-frequency input signal to generate a high-frequency output signal;
• and
• a second plurality of electrical contacts coupled to the microwave amplifier being selectively engageable with the first plurality of electrical contacts of the handle assembly;
• and
• a probe extending distally from a distal end of the handle assembly and operably coupled to an output of the microwave-signal-amplifying module;
• wherein the microwave-signal-amplifying module is selectively removable from the handle assembly.
