About SIAE Microelettronica
Italian microwave engineering with a global carrier installed base.
SIAE Microelettronica is an Italian microwave radio manufacturer headquartered in Cologno Monzese (Milan), with a global installed base across cellular carriers, broadcast networks, government microwave systems, and ISP backhaul deployments. The ALFOplus and ALFOplus²N radio families cover licensed microwave bands from 6 GHz through 42 GHz, supporting SDH and PDH legacy circuits alongside Ethernet payload, XPIC (cross-polarization interference cancellation) for capacity doubling on the same dish, and ACM (Adaptive Coding and Modulation) for graceful degradation under weather fading.
EhubAmerica stocks the most-requested SIAE SKUs in our Doral, FL warehouse alongside coordinated quoting with SIAE distribution for project-specific configurations. Common in-stock items include ALFOplus terminal hardware, antenna couplers, mounting hardware, and accessories. Specific radio frequency band combinations, polarization configurations, capacity tiers, and dish pairings are typically quoted per-project with SIAE engineering since each microwave link requires path profile work and licensing coordination with the FCC under Part 101 in the US.
The SIAE Microelettronica lineup is the practical choice for cellular carriers and tower companies building or upgrading licensed microwave backhaul between sites, broadcast engineers running high-capacity studio-to-transmitter links, ISP backhaul deployments where carrier-class link availability targets (99.99 to 99.999 percent) are required, government and utility microwave systems requiring documented licensed-band performance, and specialty applications (financial trading networks, port authorities, transit systems) where commercial off-the-shelf unlicensed gear does not meet the availability or licensing requirement.
Product lines we stock and quote
Our active SIAE Microelettronica catalog sorts into three practical categories. ALFOplus terminals licensed microwave radios across 6 GHz through 42 GHz bands with Ethernet, SDH, and PDH payload, XPIC, and ACM. Specific band, capacity, and polarization configurations quoted per-project. ALFOplus²N higher-capacity terminals for next-generation cellular and high-capacity ISP backhaul with multi-Gbps throughput per channel. Antenna and mounting accessories for ALFOplus and ALFOplus²N installations, plus consumable replacement parts and field service kits.

Frequently asked
SIAE questions, carrier-class answers.
Specific to cellular carriers, tower companies, broadcast engineers, ISP backhaul integrators, and government microwave operators specifying licensed PtP links.
Do you stock SIAE Microelettronica in Miami?
We stock common ALFOplus accessories, mounting hardware, and consumable replacement parts. Specific radio terminal configurations (band, capacity, polarization) are quoted per-project from SIAE distribution with typical lead times of 2-6 weeks depending on the configuration. Path profiles and link budget work are coordinated with SIAE engineering for any new licensed-band link.
ALFOplus versus ALFOplus²N: which should I specify?
ALFOplus is the broader workhorse for typical cellular backhaul and ISP PtP at standard Gbps capacities. ALFOplus²N is the higher-capacity next-generation terminal for multi-Gbps backhaul on the same band, often paired with dual polarization XPIC for very high capacity on a single dish. For cellular 4G LTE backhaul and most ISP PtP, ALFOplus is the right tier. For 5G backhaul, mid-haul, and high-capacity broadcast, ALFOplus²N is the recommended choice. Tell us the capacity target and we recommend the right terminal and dish size.
Can you help with FCC Part 101 licensing for a SIAE microwave link?
Yes for the basics. FCC Part 101 licensing for a US licensed microwave link requires path profile work, frequency coordination through a frequency coordinator (Comsearch, Micronet, or similar), and the FCC license application itself. We coordinate the path profile and frequency coordination handoff with SIAE engineering and the appropriate frequency coordinator. The actual FCC license is held by the licensee and we don't act as the FCC license applicant. Typical end-to-end coordination timeline is 4-8 weeks from path profile request to license grant.
What is XPIC and when do I need it?
XPIC (Cross-Polarization Interference Cancellation) is a feature that lets you run two independent data streams on the same dish using two polarizations (vertical and horizontal), effectively doubling link capacity without adding a second antenna. It's the standard upgrade path for carriers needing more capacity on an existing tower path where adding a second dish is impractical or impossible. ALFOplus and ALFOplus²N both support XPIC with dual-polarized antennas.
SIAE versus Ceragon versus Aviat: how do they compare?
All three are credible carrier-class microwave PtP manufacturers. Ceragon (Israeli) has broad global deployment and strong cellular carrier presence. Aviat Networks (US-based) has deep North American carrier installations. SIAE Microelettronica (Italian) is particularly strong in European cellular and ISP backhaul, with growing North American adoption. Feature parity across the three is generally close at the carrier-class tier; choice often comes down to specific tower or carrier preferences, existing installed base, and pricing per-project. We can quote any of the three depending on your spec.
What is the SIAE RMA process at EhubAmerica?
Send the unit with a brief problem description and the original order or invoice reference. We issue replacement within 48 hours of receipt for in-stock accessories and parts. For radio terminals, warranty cases route through SIAE service channels with typical turnaround of 2-4 weeks for warranty repair or replacement depending on the SKU. Warranty covers manufacturing defects, not damage from lightning, power surges, or tower work errors.
Let us quote your SIAE order.Same-day response on accessories.
Send us the link spec: frequency band, path distance, capacity target, polarization (single or dual XPIC), availability target, and any path profile or FCC coordination needs. We come back with terminal recommendation, dish sizing, lead time, pricing, and FCC Part 101 coordination timeline.
