RADIO QUOTE SCOPE
A radio rf amplifier request often arrives as a service name plus a watt guess. LinkScope Sourcing 32, an independent sourcing partner, turns that guess into fields a factory can answer. The desk does not stock exciters and does not decide which modulation the license allows.
Name the radio service in the buyer words: land mobile, FM broadcast, amateur, or a laboratory generator. Then write the numeric span. 144-148 MHz is not the same purchase as 450-470 MHz, even when both are called radio. Channel width, if the emission is narrow, goes in this cell.
State the exciter output in dBm and the gain the amplifier must provide. A +37 dBm radio into a 13 dB stage is a different bill of materials from a 0 dBm source into a 50 dB chain. Power rating needs the duty: continuous voice, a 0.50 duty data cycle, or a short pulse. Ask the supplier to say which one the watt number uses.
Impedance, VSWR limit, and connector gender sit together. A jumper, an attenuator, and a harmonic filter each add insertion loss. Put that loss on its own line so it is not buried inside the amplifier gain. Polarization and radiation pattern stay blank unless the radio purchase also includes the antenna.
Quantity, US destination, requested timing, currency, and a per-unit or whole-order target budget are commercial cells. Freight, duties, rack rails, a 28 V or 48 V supply, and commissioning are exclusions until the supplier marks them included. A supplier preference of high-end, mid-range, budget, or undecided is a buyer stance, not a verified grade.
Background: during April 2026 a public-safety integrator described a spare radio amplifier for a 450 MHz repeater site, quantity 6, ship to Texas. Process: the desk asked each respondent for the repeater drive level, whether 100 W meant the duplexer output or the amplifier flange, and whether the DC supply was in the price. Result: two replies that looked close were a flange rating and a post-duplexer rating, so the buyer held the comparison until both used the flange. This is a sourcing situation, not a testimonial.
Condition is a dispute the quote must not hide. A new amplifier can carry a datasheet dated in 2024 or 2025 and a support route the maker still answers. A refurbished amplifier can fill a repeater that the maker no longer builds, if the seller states hours, fan wear, and warranty months. Identity is a second dispute. An original-maker module may match the radio vendor policy. A compatible module may be quotable when gain, spurious level, and the exact repeater model are checked. Record both. Do not average them into one score.
The desk will not do three things on this page. It will not treat a family brochure as evidence for the quoted serial range. It will not move a 75 ohm television plant into a 50 ohm land-mobile sheet. It will not read Title 47 CFR Part 2 Subpart J, consulted on 2026-10-27 as question context, as an authorization of any module. If an authorization file is required, the supplier attaches the file that names the model. ISO 9001 and an NRTL mark, when relevant to the supply, are separate attachments.
Measurement accuracy belongs in the evidence pack: the power-meter model class, the calibration traceability date, and the load used, such as a 50 ohm termination rated above the wattage. Connector mating cycle limits matter when the site swaps jumpers often. Ingress protection matters when the amplifier shares an outdoor cabinet with the radio. Mounting in rack units matters when the spare must fit a 19 in tray. One rack unit remains 1.75 in. The power lines are inquiry labels, and the brief article lists the same cells in narrative form.
Ask for the allowed input window in dBm. Too much drive can push the stage past the stated compression point. Too little drive leaves the output below the power rating even when the gain number looks large.
Request the harmonic level in dBc at the rated power and the frequency where it was taken. A filter may be required. Its insertion loss is not the amplifier gain.
Male and female N parts are a common miss. A gender changer is an extra line, with its own return loss. Do not assume the photo shows the gender you need.
There is no file upload on this form. Type or paste the lines: radio model as you know it, frequency range, drive level, desired transmit power, impedance, connector, quantity, destination, and timing. Mark unknown cells as unknown. The desk circulates that text. It does not add a hidden attachment field.
Optional budget currency and a high-end, mid-range, budget, or undecided preference merge into the requirement text when the browser supports that step. They are not new backend fields.
