The width and the length of the line used to calculate the effective dielectric constant have been chosen according to the dimensions of the impedance matching
network, as will be seen in the next section.
4] produces better impedance matching
at the lower resonant frequency.
62 GHz with acceptable performance in terms of AR, impedance matching
Common gate amplifier is used as it is easy to obtain input impedance matching
40% reduction in peak clamping voltage -- 15-40% reduction in peak residual current -- 100 Ohm differential impedance matching
with no external compensation required -- Straight through routing for improved layout -- Compact 16 pin TDFN package for reduced board space
In this case, the SILSP of the proposed antenna leads to a decrease in the height of the monopole and helps the impedance matching
in a usable frequency band.
The AWL6152 module combines an InGaP HBT integrated circuit (IC) amplifier along with passive components to provide a low-cost solution that requires very few external components for biasing and none for RF impedance matching
into a 50-Ohm system.
Support is also provided for active impedance matching
circuits that ensure exact matching to any cable or device.
In previous design, external matching networks are used to achieve impedance matching
for a broader band.
Among the various antenna configurations possible, the microstrip fed slot is particularly attractive due to the features like simpler design, low profile planar structure, wider bandwidth, bidirectional/omni-directional radiation patterns and increased degree of freedom for applying impedance matching
techniques to get a wider bandwidth.
Packaged in miniature 3-mm x 6-mm dual-flat no leads (DFN) and standard small outline transistor (SOT-89) packages, MACOM's GaN in Plastic transistors operate at 50-V drain bias resulting in desirable power density and performance, high efficiency, and small impedance matching
circuits due to improved device parasitics.
In , the author adopted microstrip line as an impedance transformer to realize impedance matching
with 50 [OEMGA], and the transmission loss caused by the very narrow microstrip line has to be considered carefully.
