Overview
The Vaunix TS-LPD-752-16 is a compact, miniature 75 Ω, 2-way passive RF power divider engineered for high-reliability signal distribution in demanding test and measurement environments. Based on precision-matched lumped-element topology, it operates over a broadband frequency range from DC to 2.5 GHz with excellent amplitude balance, phase tracking, and port-to-port isolation. Designed for integration into automated test systems, production line validation setups, and field-deployable instrumentation racks, the TS-LPD-752-16 maintains stable electrical performance across temperature extremes (–40 °C to +85 °C) and exhibits low insertion loss (≤3.5 dB typical) and tight VSWR (≤1.35:1 typical) — critical parameters for maintaining signal integrity in multi-path RF stimulus and monitoring configurations.
Key Features
- Compact form factor (1.25″ × 0.75″ × 0.35″) optimized for space-constrained ATE and modular PXIe-based RF test platforms
- 75 Ω impedance architecture compatible with broadcast, CATV, satellite communications, and legacy telemetry infrastructure
- Passive, unpowered design ensures zero DC bias requirements and immunity to electromagnetic interference (EMI) from active circuitry
- SMA female connectors provide repeatable, high-cycle mating performance (≥500 insertions) per MIL-STD-348B specifications
- RoHS-compliant construction and CE marking support global regulatory compliance for industrial and commercial deployment
- Thermally stable ceramic substrate minimizes drift in amplitude/phase balance over operational temperature gradients
Sample Compatibility & Compliance
The TS-LPD-752-16 is validated for use with standard 75 Ω coaxial cabling (e.g., RG-6, RG-11, LMR-400) and interfaces seamlessly with spectrum analyzers, vector signal analyzers, RF signal generators, and channel emulators operating within its specified bandwidth. It supports signal routing in Wi-Fi 6E (5.925–7.125 GHz band pre-filtering stages), 5G NR FR1 (sub-6 GHz) conformance testing, LTE-A Pro MIMO OTA calibration paths, and satellite communication ground station monitoring loops. The device conforms to IEC 61000-4-3 (radiated immunity), EN 55032 (EMC emissions), and meets mechanical shock/vibration requirements per IEC 60068-2-6 and IEC 60068-2-27 for stationary laboratory and light-industrial environments.
Software & Data Management
As a passive RF component, the TS-LPD-752-16 requires no firmware, drivers, or host software. Its deterministic RF behavior enables traceable calibration workflows when integrated into systems governed by ISO/IEC 17025-accredited laboratories. When deployed in automated test sequences (e.g., NI TestStand, Keysight PathWave), the divider’s consistent insertion loss and isolation characteristics contribute directly to measurement uncertainty budgets. Calibration certificates—traceable to NIST or EU NMIs—can be issued upon request, documenting S-parameter measurements (S21, S31, S23) across the full frequency band at 25 °C ambient. Full audit trails for calibration history, environmental exposure logs, and usage cycles are supported under GLP/GMP-aligned data governance frameworks.
Applications
- Parallel path excitation in multi-antenna Wi-Fi 6E and 5G FR1 production test fixtures
- Reference signal splitting for dual-channel phase-coherent receiver characterization
- Signal monitoring taps in satellite transponder downlink chains (L-band, S-band)
- Impedance-matched feed networks for phased array element calibration benches
- Redundant signal routing in mission-critical broadcast transmission monitoring systems
- Low-noise intermediate-frequency (IF) distribution in software-defined radio (SDR) test beds
FAQ
Is the TS-LPD-752-16 suitable for 50 Ω systems?
No — it is strictly a 75 Ω impedance device. Direct integration into 50 Ω systems requires impedance-matching networks and introduces measurable mismatch loss and potential standing wave distortion.
Can this power divider handle pulsed RF signals with high peak-to-average power ratios?
Yes — as a passive, thermally robust component with no active semiconductors, it supports peak power handling up to +30 dBm (1 W) continuously and higher short-duration pulses, provided average dissipation remains within thermal limits.
Does Vaunix provide S-parameter data files (Touchstone .s2p) for system simulation?
Yes — measured broadband S-parameter datasets (DC–2.5 GHz, 10 MHz step) are available upon request for ADS, HFSS, and CST model integration.
What is the maximum recommended input power level for continuous operation?
The unit is rated for continuous input power up to +30 dBm (1 W) at 25 °C ambient; derating applies above 60 °C per MIL-STD-2164A thermal guidelines.
Is the TS-LPD-752-16 qualified for aerospace or defense applications?
While not MIL-SPEC screened, its construction, materials, and test reports align with screening levels defined in MIL-PRF-32535 for Class B passive RF components; full qualification requires customer-specific lot testing.
