X3C35F1-03S

The X3C35F1-03S from Anaren Microwave is a low-profile, high-performance 3 dB, 90° hybrid coupler in a manufacturing-friendly surface mount package. It is designed for applications requiring tight amplitude and phase balance, such as balanced power and low noise amplifiers, and signal distribution.

This coupler operates over a frequency range of 3200-4200 MHz, with specific performance metrics detailed for the 3300-3800 MHz band. It features high isolation (23 dB min at 3300-3800 MHz) and very low insertion loss (0.20 dB max at 3300-3800 MHz). The VSWR is kept low, at 1.15 max for 3300-3800 MHz, and amplitude balance is tight (± 0.30 dB at 3300-3800 MHz).

Designed for high power applications, the X3C35F1-03S can handle up to 25 watts average CW power at 95°C. It operates within a wide temperature range of -55°C to +150°C. The materials used have coefficients of thermal expansion compatible with common substrates like FR4, G-10, RF-35, RO4003, and polyimide, ensuring reliable performance in various environments.

The part is available on tape and reel, making it suitable for pick-and-place manufacturing processes. It is produced with a RoHS compliant tin immersion finish.
