RF Directional Couplers are designed to couple a specific amount of electromagnetic power in a transmission line to a secondary line enabling the signal to be used in another circuit. The coupler types are Coupler-with Filter, Dual Band-Dual Path, and Standard with frequencies ranging from DC to 40 GHz. The coupling factor ranges from -20 dB to 49 dB with applications being AGSM, AMPS, CDMA, Cellular, DCS, DECT, E-GSM, General Purpose, GSM, LTE, Military, PCN, PCS, PDC, PHP, S-Band Radar, Telecom, W-CDMA, Wireless LAN, WLAN, and X-Band Radar.

See when an inductor behaves linearly, how DC bias and saturation reduce inductance, and which current and temperature curves to check.
