Overview

  • 4-way RF splitter combiner
  • Frequency range: 17 GHz to 32 GHz
  • Insertion loss (excess of 6.0 dB): −1.7 dB at 22 GHz to 27 GHz
  • Return loss (S1): −17 dB at 22 GHz to 27 GHz
  • Isolation: −17 dB at 22 GHz to 27 GHz
  • 2.460 mm x 2.460 mm x 0.500 mm, wafer level, chip-scale package

The ADAR5000 is a 1-to-4 Wilkinson power splitter that is designed for space-sensitive microwave signal distribution applications. Excess insertion loss ranges from −1.5 dB to −2.5 dB from 17 GHz to 32 GHz. The four outputs are matched in both phase and amplitude, making the ADAR5000 ideal for signal distribution applications requiring low time skew between channels. The ADAR5000 can also be used as a combiner, combining input signals at the P1, P2, P3, and P4 ports to an output at the S1 port. The ADAR5000 is housed in a compact, 2.460 mm x 2.460 mm x 0.500 mm WLCSP, which makes it ideal for use in planar, phased-array antenna systems that require a tight pitch between elements.

The ADAR5000 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

    • Microstrip traces
    • Through, open, and short calibration paths

    Product Details

    The ADAR5000-EVALZ is a copper clad, 4-layer printed circuit board (PCB) fabricated from 0.254 mm (10 mil) thick, Rogers 4350B. The central core is prepreg, and there is an unused FR4 layer on the underside, which forms a nominal thickness of 1.574 mm (62 mils). The P1, P2, P3, P4, and SUM ports on the ADAR5000-EVALZ are populated with 2.92 mm, female coaxial connectors, and the corresponding microstrip RF traces have a 50 Ω characteristic impedance. To calibrate board trace losses, a through calibration path is provided between the J7 and J6 connectors. Open and short paths are provided on the J8 and J9 connectors. Refer to Table 1 and Figure 3 in the user guide for the through calibration path performance.

    For full details on the ADAR5000, see the ADAR5000 data sheet, which must be consulted in conjunction with the user guide when using the ADAR5000-EVALZ.
