Both the PT and HF series are stable-phase RF coaxial cables under the Times Microwave brand. Their core differences lie in positioning, performance parameters, and applicable scenarios.
HF series stable phase cable
The HF series is a precision test-grade phase-stabilized cable, with typical models such as HF190. Its operating frequency covers DC-26.5GHz. It utilizes a low-loss single-core inner conductor and an ultra-low-density PTFE insulation layer. The dual-layer shielding structure boasts a shielding efficiency of over 90dB. It primarily caters to the amplitude and phase stabilization requirements of conventional RF testing scenarios and is a widely used general-purpose test cable in the industry.
PT series phase-stabilized cable
The PT series belongs to the high-end specialty stable phase cables, with typical models such as PT-047, specifically designed for demanding scenarios such as space satellites. Its operating frequency can reach up to 70GHz, and its operating temperature range spans from -65°C to +150°C. It can withstand over 1 million cycles of flexible bending tests, boasts a more compact and sturdy design, and exhibits superior phase stability in high-frequency and extreme environments.
