Discover Focus Microwaves' wideband fundamental tuners. The C-Series (Computer-Controlled Microwave Tuners) feature one to three wideband probes, enabling exceptionally broad frequency coverage—ideal for high-power and wideband noise applications.

Designed for precision, the tuner's long-lasting RF probes ensure optimal tuning accuracy while eliminating spurious resonances. The integration of multiple probes within a single tuner provides ultra-wideband coverage, making it a versatile solution for demanding RF applications.

Calibrating tuners for Network Analyzers presents challenges due to high reflections and low losses, affecting S-parameter measurements. At Focus Microwaves, we advocate for TRL (Thru-Reflect-Line) calibration as essential for precise results, unlike the less reliable SOLT and ECal methods. Our comprehensive TRL calibration kits cover 0.3 to 110 GHz and support connector types including 7/16, N, APC-7, 3.5mm, 2.9mm, 2.4mm, 1.9mm, WR-15, and WR-10. Compatible with all commercial network analyzers, these kits ensure reliability and accuracy, crucial for dependable VNA measurements.

Southwest Microwave offers a broad family of SSBP multi-coax contacts and assemblies to address RF/microwave packaging miniaturization and flexibility challenges. These push-on coax contacts simplify interconnections and cabling while offering greater system reliability than the alternative of mating a large array of standard coax connectors. These SSBP coax contacts were designed to fit into standard off-the-shelf MIL-DLT-38999 and MIL-DTL-24308 D-Sub connectors and are interchangeable with standard signal contacts available in 20 HD, 20, 16, 12, 8 sizes to accommodate a variety of performance requirements.

Contact us for flexible cable assemblies and harnesses for OTS MIL-DTL-38999 series I, II, III, and IV or MIL-DTL-24308 D-sub connectors. All size 20 contacts are sold on cables.

Our 2 Series cable assembly showcases excellent phase stability against bending, developed with microwave/mmWave measurement environments in mind. 

Its flexibility means low repulsion, reducing the load on the measured object

Focus Microwaves' DLP (Dynamic Load Pull) is a cutting-edge platform for active load pull measurements, optimized for accuracy, speed, and reliability. Supporting frequencies up to 40GHz and beyond, it offers a versatile solution for CW and pulsed signal applications. The DLP enables fundamental and harmonic tuning, time domain measurements, and advanced behavioral modeling. With integrated options for DC IV and pulsed IV measurements, this one-box system is ideal for all stages of device characterization and testing, from initial development to final product testing. Its intuitive interface and industry-leading calibration techniques ensure precise and efficient measurements.

The Low Frequency Tuner (LFT) is a unique product technology using M algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors. The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.
