When receiving a faint signal from a satellite hundreds of kilometers above us, the RF Low Noise Amplifier (LNA) must have very low noise and high gain. When making a call in a moving vehicle, the RF circuits must perform in a dynamically changing environment to maintain safety and connecti...

The circuit schematic is simulated with OrCAD 9.2, implemented by 4-layer PCB, and tested by Agilent's network analyzer from 10MHz to 1GHz. The gains are 8dB for channel 1 and 14dB for channel 2, and the bandwidth is up to 460MHz. Input and output VSWR are about 2:1 or less for ...
Antennas, waveguids and RF filter structures are captured in a special schematic entry and layout canvas which are both very tightly integrated. The shape of the layout (metal on PCB) defines the function of the structures themselves. To capture the behavior of the circuit, the layout needs ...
The high gain and broadband performance of these devices make them ideal for large- signal, common- source amplifier applications in 28 volt base station equipment. These devices have a 2-stage design with off-chip matching for the input, interstage and output networks to cover the desired ...
Figure 10: Simplified schematic of a push-pull amplifier. The gain of a push-pull amplifier is same as that of an individual amplifier, whereas the output power is twice that of an individual amplifier. Push-pull connection is frequently used for combining power of individual amplifiers. ...
