Abstract: A liquid lens with flexible transparent active layers on both sides of a fluid is transformed along two distinct deformation axes. The flexible transparent active layers include piezoelectric materials that actuate the lens in response to applied voltage(s). The piezoelectric properties and actuation mechanism of the transparent layers are arranged to deform the lens cylindrically along different axes resulting in a net spherical deformation or a combination of spherical and cylindrical deformation with substantially less distortion than spherically deforming layers. The piezoelectric active layers may be polymer or ceramic with isotropic or anisotropic mechanical stiffness. Alternatively, a pair of transparent, internal layers are positioned between the front and rear surfaces. The active layers, front and/or rear, are dual layers affixed together with an adhesive or single layers.

Abstract: A packaged RF amplifier device includes input and output leads and a transistor die. The transistor die includes a transistor with a drain-source capacitance below 0.1 picofarads per watt. The device also includes a conductive connection between the transistor output terminal and the output lead, and a baseband termination circuit between the transistor output terminal and a ground reference node.

Except for a minimal impedance transformation associated with the conductive connection, the device is unmatched between the transistor output terminal and the output lead by being devoid of impedance matching circuitry between the transistor output terminal and the output lead.
