D-COAX, Inc. has introduced high performance TDR – VNA Probe assemblies through 44GHz in the 2 configurations in the greater metropolitan area of Portland Oregon. Testing for small discontinuities on non-planar PCBs is now possible on a 40GHz VNA or very fast TDR because of the durable and repeatable probe design. The probes deliver excellent uncorrected return loss and low insertion loss. The OmniJet probe 40 GHz insertion loss is better than -1.5dB and the return loss is better than -10.0dB at 40GHz. All D-COAX products are made in the USA. For more information, visit http://www.d-coax.com/.
