摘要:
Power amplifiers and methods of coating a protective film of alumina (Al2O3) on the power amplifiers are disclosed herein. The protective film is applied through an atomic layer deposition (ALD) process. The ALD process can deposit very thin layers of alumina on the surface of the power amplifier in a precisely controlled manner. Thus, the ALD process can form a uniform film that is substantially free of free of pin-holes and voids.

摘要:
An amplifier circuit (20) uses a series transistor (38) to couple the output of an amplifier (26) to a tuned circuit load (40) and to act as a variable resistance. In one embodiment for a multi-band receiver, multiple series transistors (38, 42) are switched for connecting different tuned circuits (40, 44) to the amplifier's output, and an activated one of the series transistors receives a gate voltage that varies its resistance so as to achieve gain control. An activated series transistors can also provide a resistance that stabilizes the amplifier (26).

The present disclosure is related to an electronic assembly in a stacked configuration. Electronic components are formed on substrates at each level of the stacked configuration. Electromagnetic shield compartments may be provided which substantially encapsulate the electronic components. Conductive vias are formed within the substrates on each level of the stacked configuration and coupled to one another so that the electromagnetic shields at each level of the stack can couple to a common node.

摘要:
A dual channel receiver (100) includes a front end bandpass filter (120) that has a front end bandwidth, a first mixer (130), a second mixer (135), and two essentially identical receiver back ends (190, 195). The front end bandpass filter splits a received signal into a first signal (121) and a second signal (122) of essentially equal signal strengths and provides out of band isolation between first and second signal outputs (123, 124). The first mixer is coupled to the first signal and to a high side injection signal (131), and generates a first mixer output signal (132). The second mixer is coupled to the second signal and to a low side injection signal (136), and generates a second mixer output signal (137). Each of the two essentially identical receiver back ends is coupled to one of the first and second mixer output signals.
