Part details & applications

The ADAR5001 is a 1-to-2 Wilkinson power splitter that is designed for space-constrained microwave signal distribution applications. Excess insertion loss ranges from −1.0 dB (from 10 GHz to 18 GHz) and −1.1 dB (from 18 GHz to 27 GHz). The two outputs are matched in both phase and amplitude, making the ADAR5001 ideal for signal distribution applications requiring low time skew between channels. The ADAR5001 can also be used as a combiner, combining input signals at the P1 and P2 ports to an output at the S1 port. The ADAR5001 is housed in a compact, 1.460 mm × 1.460 mm × 0.500 mm WLCSP, which makes it ideal for use in planar, phased-array antenna systems that require a tight pitch between elements.

The ADAR5001 is fabricated on a passive silicon process, and it is specified to operate from −40°C to +85°C.

APPLICATIONS

General-purpose microwave signal distribution
Phased-array satellite communication (SATCOM) systems
Phased-array radar systems
