Transmission Line Filter

Design of a fifth-order line and stub low-pass microwave filter. Butterworth and Chebyshev responses; demonstrates tolerances to line impedance, load match and insertion loss.

Directional Coupler Operation

Demonstrates the operation of lossy and lossless directional couplers with a variety of mid-band coupling values over a range of port match conditions.

Microstrip Directional Coupler

The applet encompasses the latest published design rules for accurately designing microstrip broadside, coupled-line directional couplers in the frequency range 1 to 20 GHz.

Mixer Spurii

Intermodulation component generation up to the seventh-order in single diode, balanced and doubly balanced mixer types as a function of LO and signal drive levels.
