A packaged radio frequency (RF) module is disclosed. The module can include a substrate, a first die electrically and mechanically attached to the substrate, a second die electrically and mechanically attached to the substrate, an encapsulating material, and a lid attached to the substrate. The first die comprises a silicon-based die, such as an RF switch die, and the second die comprises a compound semiconductor die, such as an RF amplifier. The encapsulating material can protect electrical connections between the first die and the substrate. The substrate and the lid at least partially define an air cavity within which the first and the second die are mounted. An active surface of the second die is exposed to the air cavity.

Radio frequency communication systems

An integrated RF switch module including a package customized to include at least one trace. The trace includes one or more of at least one connection pad and at least one landing pad. At least one switching die is connected to the at least one connection pad. At least one device is connected to the at least one landing pad, the at least one device configured to enhance the performance of the switching die.

Integrated switch module

An eyepiece adapter mechanism for providing a quick positive engagement to an interfacing instrument such as a B-styled endoscope. The adapter mechanism comprises a rigid back plate for providing a permanent attachment for the mechanism. A C-clip retainer positioned within a circumferential chamber of the back plate acts as a locking ring under the elastic force of the C-clip material itself to provide a grip around the interfacing instrument when installed into the back plate. An outwardly protruding portion of the C-clip, acting as a lever, releases the interfacing instrument when the level is moved toward a fixed post located a predetermined distance from the lever to facilitate single handed operation. An alternate embodiment provides a quick attach/release adapter without an eyepiece and employing a C-clip retainer.
