LCBandpassTransformer (Bandpass Transformer)

Symbol

Summary

A bandpass transformer provides a bandpass (pseudo-lowpass) frequency response between the input (pin 1) and output (pin 2) ports. The source or load terminations must be real and unequal.

Parameters

Fp1	Frequency at left passband edge	GHz	1
Fp2	Frequency at right passband edge	GHz	2
N	Network order	None	3
ResponseType	Type of frequency response	None	Maximally Flat
Rg	Source resistance	Ohms	50
RL	Load resistance	Ohms	25

Matching Assistant Usage

For general information, refer to Matching Assistant. The terminations must be unequal or no network is synthesized. For equal terminations, use a doubly-terminated filter topology. Network order results in 2×N components.

Simulation Assistant Usage

For general information, refer to Simulation Assistant.

Yield Assistant Usage

For general information, refer to Yield Assistant.

Display Assistant Usage

For general information, refer to Display Assistant.

Example

A bandpass transformer (N=3) was designed for a passband between 1 GHz and 2 GHz with a source resistance of Rg=50 Ohms and a load resistance of Rl=20 Ohms. See Bandpass Transformer.
