Quadrature hybrid coupler delivers 30 W, 3 dB for mobile communications

Available in 2100 MHz and 2700 MHz, AVX PC series couplers feature a 1 mm profile and exhibit excellent isolation, low parasitics, and heat dissipation

Two wideband, 3 dB, 90° hybrid couplers comprise a 2100 MHz device for 1.5 to 2.1 GHz and a 2700 MHz device for 2.1 to 2.7 GHz. Based on AVX’s MLO technology, which enables the integration of high Q passives in low cost, high density interconnect components, PC series power couplers exhibit excellent isolation and high reliability to comply with JEDEC and MIL standards.

Expansion-matched to PCBs and supplied in surface mountable 2025 size land grid array (LGA) packaging, the multifunctional, low profile PC Series couplers also exhibit low parasitics, exceptional heat dissipation, and excellent solderability.

Designed to support a broad range of mobile communications applications, including: cellular phones, pagers, distributed control systems (DCS), geographic positioning systems (GPS), vehicle location systems, and wireless LANs, PC Series hybrid couplers are sutiable for use in attenuators, phase shifters, LNAs, balance amplifiers, and signal distribution equipment.

“Utilising MLO technology, the new PC Series 3 dB, 90° quadrature hybrid couplers are a valuable extension to AVX’s coupler catalogue, which previously consisted exclusively of thin film directional RF couplers,” said Larry Eisenberger, senior marketing application engineer at AVX. “MLO technology ...provides high Q performance in low cost, high density interconnect components.”

PC Series 3 dB, 90° hybrid couplers are rated for 30 W maximum power handling and operating temperatures spanning -55°C to +85°C. The devices measure 6.35 x 5.08 x 1.0 mm.
