A medical device includes a handle assembly and a probe-and-amplifier assembly. The handle assembly includes a handle body defining a chamber therein. The probe-and-amplifier assembly includes a probe and a microwave amplifier unit. The probe extends distally from the distal end of the handle assembly. The microwave amplifier unit is disposed within the chamber. The microwave amplifier unit and the probe are mechanically coupled to one another to form a unitary body. The probe-and-amplifier assembly is selectively removable from the handle assembly.

A medical device includes a handle assembly including a distal end, a probe extending distally from the distal end of the handle assembly, and a microwave amplifier unit disposed within the handle assembly. The microwave amplifier unit is adapted to amplify a high-frequency input signal to generate a high-frequency output signal to be transmitted to the probe.

An end effector assembly includes a pair of opposing jaw members movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes a microwave antenna assembly and a shielding member including a metallic plate coupled to ground and a dielectric material. The end effector assembly also includes a splitter configured to receive an active signal from a source of microwave energy and split the active signal into a first signal transmitted to the microwave antenna assembly in one of the jaw members and a second signal transmitted in the microwave antenna assembly in the other jaw member.

A multi-layer printed circuit board includes a first layer stack and a second layer stack coupled to the first layer stack. The first layer stack includes a first electrically-insulating layer, a second electrically-insulating layer, and a first electrically-conductive layer disposed between the first and second electrically-insulating layers. The second layer includes a third electrically-insulating layer and a second electrically-conductive layer. The first layer stack and/or the second layer stack include a cut-out area defining a void that extends therethrough. The multi-layer printed circuit board further includes a first signal layer disposed in association with the first electrically-insulating layer of the first layer stack or the third electrically-insulating layer of the second layer stack, a second signal layer disposed in association with the second electrically-insulating layer of the first layer stack, and a device at least partially disposed within the cut-out area and electrically-coupled to the first and second signal layers.

A method of manufacturing a printed circuit board includes the steps of providing a first layer stack including a first electrically-conductive layer and a first electrically-insulating layer and providing a second layer stack including a second electrically-insulating layer. The first electrically-conductive layer is disposed on the first surface of the first electrically-insulating layer. The second electrically-insulating layer includes one or more electrically-conductive traces disposed on a first surface thereof. The method also includes mounting a device on the first surface of the second electrically-insulating layer such that the device is electrically-coupled to at least one of the one or more electrically-conductive traces, and providing the first layer stack with a cut-out area defining a void that extends from the second surface of the first electrically-insulating layer to the first surface of the first electrically-conductive layer. The cut-out area is configured to receive at least a portion of the device therein.
