Abstract
Disclosed are a microstrip-type BALUN (BALance to UNbalance transformer), broadcast receiving apparatus using the same, and a method for forming the same. The BALUN includes a board and a microstrip line formed on the board for transforming an input unbalanced signal into a balanced signal. Since the microstrip-type BALUN is realized by a microstrip line which is a distributed constant line, the microstrip-type BALUN has an excellent performance even for high-frequency signals. Similarly, a broadcast receiving apparatus to which a microstrip-type BALUN is applied also has an excellent performance for high-frequency broadcasting signals.
Claims15
A balance to unbalance transformer (BALUN) comprising:
- a board;
- and
- a microstrip line formed on the board for transforming an unbalanced input signal into a balanced signal.
A broadcast receiving apparatus comprising:
- a board;
- a first broadcasting signal processing element formed on the board for outputting an unbalanced broadcasting signal;
- a second broadcasting signal processing element formed on the board for receiving a balanced broadcasting signal as an input;
- and
- a balance to unbalance transformer (BALUN) comprising a microstrip line on the board for transforming the unbalanced broadcasting signal output from the first broadcasting signal processing element into the balanced broadcasting signal and outputting the balanced broadcasting signal to the second broadcasting signal processing element.
A method of forming a balance to unbalance transformer (BALUN) comprising forming a microstrip line on a board for transforming an unbalanced input signal into a balanced signal.
