DARK SPLIT · WRITTEN BRIEF
Send LinkScope Sourcing 34 the isolator line
LinkScope Sourcing 34 reads a written procurement brief. The form on this page is the working channel for frequency range, connector, power, quantity, destination, and timing. It is a full contact layout, not the narrow dialog used elsewhere on the site.
How a brief is handled
- Channel
- The form on this page posts to the existing feedback action. There is no separate upload service and no published social account for quotations.
- Put a work email in the form so the desk can reply. This site does not publish a standalone mailbox, because a second address would split the record away from the brief.
- Telephone
- No telephone number is published. If you want a call back, write a phone number and a window in the form. A call is not scheduled until a person reads the brief.
- Street address
- No street address or map pin is published. Do not ship hardware to this website. Destination in the brief means your receiving site, not an office of this desk.
- Review window
- Briefs are read on US business days. The page does not state a same-day reply, a ship date, or a reserved factory slot. Timing in your text is a request for the supplier to confirm.
What to prepare before you send
List frequency range, impedance, insertion loss and isolation thresholds, VSWR or return loss, forward power rating, termination rating, and SMA gender. Example open values for a 2026 bench row are 2.0 GHz to 4.0 GHz, 50 ohm, 0.6 dB insertion loss ceiling, 18 dB isolation floor, 1.30:1 VSWR, 10 W forward, 2 W load, and SMA female. Polarization, radiation pattern, and gain stay off this row unless the bill also contains an antenna or an amplifier. Mounting and environmental rating belong here when a bracket or an outdoor cabinet is real. Ingress protection is a cabinet code unless the isolator body is exposed. Quantity and the US destination decide freight. Expected delivery timing should name a quarter of 2026 or say the date is open.
An optional budget needs an amount or range, a currency, and whether it is per piece or for the whole order. High-end, mid-range, budget, or not yet decided is your preference for the kind of supplier to approach. It is not a grade already earned by a factory, and you do not need a live price to submit. Connector mating cycle and calibration traceability are worth a sentence if you will retest the lot on a vector network analyzer.
Three limits travel with every brief. Out-of-band isolation is not the in-band number. A 25 C plot is not a 4 K result. The internal load rating can be smaller than the forward rating. Compliance files are requested, not assumed: 47 CFR Part 2 Subpart J is where a transmitter grant would be checked, and a passive isolator often has none. ISO 9001 evidence needs a body and an expiry if a factory offers it. This desk has not audited that certificate. Read the port-map fields or the method notes if you want the boundaries before you type. The dialog elsewhere uses the same field names in a narrow frame. This page keeps the handling notes beside the form.
