RF test hardware and production test systems, built to the measurement
QIANSPEC designs and manufactures shielded enclosures, RF components, and automated test stations for wireless device production. Founded in Shenzhen in 2014, we supply the hardware that sits between your instrument and your product — and we specify it against your device, not a catalogue.
What we build
Four product lines, each addressing a different point in the test chain.
- RF shielded enclosures — benchtop manual boxes through pneumatic production cells and two-position drawer stations, 0.5 GHz to 18 GHz depending on configuration.
- RF components — step and programmable attenuators, 4×16 matrix switches, SPDT switches, high-pass filters, low-noise amplifiers, and phase-stable test cables.
- Production test systems — multi-antenna coupling, automated RSSI, UWB, ECG, PCBA functional test, RSE screening, and vision inspection.
- Control and interface accessories — USB and TTL control boards, self-mating test connectors, and line communication antennas.
How we specify
A shield box is not a commodity. The same enclosure performs differently depending on what is inside it, which bands matter, and how the feed-throughs are filtered. So we start from six questions:
- What is the device, and what are its largest dimensions with a case or sleeve fitted?
- Which bands have to be measured, and what isolation is required at each?
- Which instruments are in the chain, and what is the coupling path?
- How does the device sit in the fixture, and who loads it?
- What cycle time does the line allow?
- Which interfaces cross the wall — SMA, USB, RJ45, DC, optical?
Specifications that depend on the answer are stated as confirmed per project rather than published as a single figure. Where a datasheet has an open point, we say so.
Where the hardware goes
Our equipment is used in phone, tablet, laptop, wearable, TWS, router, ONT, payment terminal, and appliance production, and in the RF labs that support them.
- 5G NR, LTE, Wi-Fi 6E, Bluetooth, UWB, GPS, and NFC radio paths
- RSSI, transmit power, EVM, sensitivity, and radiated spurious emission measurements
- Audio and abnormal-noise screening for speakers, motors, and appliances
- ECG front-end validation for wearable health devices
- PCBA functional test and firmware programming after SMT
