Frequently Asked Questions
What is a 3 dB 90 degree hybrid coupler?
A 3 dB 90 degree hybrid coupler is a four-port passive RF component that divides an input signal between two output ports with approximately equal power and a nominal 90-degree phase difference. It can also be used to combine two properly phased signals.
What frequency range do KRYTAR ULTRA+ hybrid couplers cover?
The current KRYTAR ULTRA+ 90 degree hybrid coupler family covers frequencies from 0.5 GHz to 40 GHz.
Which KRYTAR hybrid coupler covers 2–18 GHz?
The KRYTAR ULTRA1830 covers 2–18 GHz, with ±0.3 dB amplitude imbalance, ±4-degree phase imbalance and insertion loss below 1.2 dB.
Which model covers 1–18 GHz?
The KRYTAR ULTRA1831 covers 1–18 GHz and provides more than 19 dB isolation.
Which KRYTAR model has the lowest listed insertion loss?
The ULTRA3060200 has insertion loss below 0.7 dB over its 6–20 GHz frequency range.
Which KRYTAR 90 degree hybrid couplers operate to 40 GHz?
The ULTRA3100400 and ULTRA3100400K both operate from 10 to 40 GHz. The principal difference is the connector type.
