There are two special cases of lossless terminated lines which we will be discussing in this blog. Assume that one of the transmission lines is shorted at one end that means impedance ZL=0 and the other one is open at …
Transmission line terminated by a load Let’s consider a simple example of a transmission line terminated by a load. The transmission line consists of a pair of conductors (wires) separated by a dielectric material. At one end, the transmission line …
When does Reflection occur in Transmission Line? Impedance mismatch in transmission line can cause impedance mismatch which is the cause of reflection. A wave travelling through transmission will obviously face characteristic impedance. Read more about characteristic impedance. When there is …
In the previous blogs, we discussed transmission line time domain equations using the phasor formula. In the first case assuming there is no reflection we showed wave propagation and second case we showed the condition of the standing waves when …
In the previous blog we discussed about Transmission Line Time Domain Equations where we showed how to convert the phasor equations to time domain equation and proved the wave propagation. Example to prove Reflection Voltage We have a lossless transmission …
TDD Merits Transmitters are turned off during reception, so the two paths don’t interfere. TDD allows direct peer-to-peer communication between two transceivers hence no need for the system between them. Only one band is allocated so we don’t need to …
Frequency Division Duplexing In Frequency Division Duplexing is a full-duplex model of transceiver where different bands of frequencies are utilized for Tx and Rx and the data is transmitted and received at the same time. Bandpass filters are used to …
Time Division Duplexing (TDD) In the previous blog, we discussed about the basic structure of the transceiver and the duplexer block. Duplexer acts as a decision block like a switch between the transmitter and receiver part. There are different types …
What is a Transceiver? A transceiver is a combination of transmitter and receiver, hence the name transceiver. The transmitter and receiver share the circuitry. It can both transmit and receive radio waves to communicate with another device. Transceivers are widely …
Previously, Link budget calculations for SATCOM have been presented for both downlink as well as uplink, where we discussed key parameter ‘SNR’ of any communication link. For details of SNR calculations, read here: Link budget calculations for SATCOM – Downlink …
