Broadband MMDS Relay Transmitter

Guilin Aiwei Electronic Equipment Co., Ltd. offers a broadband MMDS relay transmitter operating from 2500 to 2700 MHz, the standard MMDS frequency allocation used for multipoint video distribution and wireless broadband backhaul. Available power levels span 10 W, 20 W, 50 W, 100 W, and 200 W, selectable to match link-budget requirements. An Automatic Gain Control (AGC) function maintains output stability against input-level variation. The unit is designed for integration into existing transmitter chains, suggesting standard rack or cabinet mounting with common RF and monitoring interfaces.

MMDS transmitters in this class typically employ solid-state LDMOS or GaN final amplifiers with harmonic filtering to meet mask compliance. The AGC loop likely samples output power and adjusts driver stages to hold level within a defined dB window, though the exact AGC range and attack time are not stated. Heat management depends on power variant, with 200 W units requiring forced-air or liquid cooling. The 2500 to 2700 MHz band sits adjacent to Wi-Fi and LTE allocations, so spurious and adjacent-channel emissions control are critical design considerations.

Primary buyers include telecom operators extending coverage to rural areas, cable operators using MMDS for last-mile video delivery, and government or enterprise networks requiring point-to-multipoint broadband. Power choice correlates with terrain and population density: 10 to 20 W for fill-in cells, 100 to 200 W for main hub stations. The supplier mentions FOB and CIF terms, but exact Incoterms, lead time, and MOQ must be confirmed directly. ISO and CE certifications are referenced; buyers should request certificate numbers and scope to validate current validity.

Guilin Aiwei Electronic Equipment Co., Ltd. is located at No.13-1, Kongming Road, Guilin, Guangxi, 541004, China. The supplier carries both imported and harbor trust tiers on the platform, with a response rate of 0.00 percent and zero average response hours. The Guilin location in central-southern China is outside the main Shenzhen-Shanghai electronics corridor, which may affect component supply-chain proximity but also indicates specialist broadcast-equipment manufacturing heritage in the region.

The listing does not state year of establishment, factory size, R and D headcount, annual revenue, or named clients. No specific ISO certificate numbers, CE declaration of conformity references, or test-house reports are provided. Buyers should conduct independent verification of the supplier's manufacturing capability, request a factory audit, and confirm whether the company designs the RF amplifier chain in-house or sources from third-party module makers. The address is a city-road location rather than an industrial park name, so clarify whether this is administrative office, factory, or both.
