Anaren Launches New Line of Xinger(R)-III Brand, Surface-Mount Doherty Combiners for Wireless Amplifiers

Available in models covering 600MHz-2700MHz — and measuring only 6.35 x 5.08mm (P-size) or 14.2 x 5.08mm (E-size) — Anaren's revolutionary new SMT Doherty combiners are up to 1/10th the size of printed Doherty implementations.

Our Doherty combiners are another in a long line of 'traditional' wireless components that we've revisited and re-packaged using our Xinger stripline approach, says Anaren Wireless Group product line manager Bo Jensen. As with other Xinger parts, our customers will find multiple value-added features with these — from smaller footprints, to lower or comparable insertion loss characteristics, to vastly improved repeatability over PCB-printed Doherty combiners.

For amplifier OEMs, who typically 'print' Doherty combiners directly onto PCB material — Anaren's new surface-mountable components offer distinct advantages, including:

> Smaller footprint — provides space for additional components/functionality or for the use of asmaller overall design

> Lower insertion loss — in a fraction of the space, achieve the same loss achievable with thick, expensive, high-performance PCB

> Superior unit-to-unit consistency — Xinger-brand components are pre-tested and offer highly repeatable performance compared to the variability seen with low-cost PCB manufacturing

> The option to choose less costly PCB — switching to an SMT solution lets the eOEM use a standard FR4-type board material (no more of overcompensating for poor insertion loss of printed combiners by using top-of-the-line board)

> High reliability — our softboard SMT solution matches the CTE characteristics of PCB

> Xinger-brand Doherty splitters (5dB couplers) available, as well — to save additional time and trouble, when the OEM is developing an asymmetrical Doherty implementation

> Readily available — As with other Anaren standard components targeted to the wireless market, this new line is available through Anaren's authorized, stocking distributors: Richardson RFPD (worldwide), Avnet (Asia), and BFI Optilas (Europe).
