Kaelus dual-band 1800/2100MHz tower mounted amplifier

Kaelus is an RF conditioning and passive intermodulation (PIM) test and measurement manufacturer with roots in Australian RF specialist Triasx (management buyout in 2005, later part of Smiths Interconnect), unified under the Kaelus name in 2010 together with Allrizon, Track Microwave and Summitek. Kaelus changed hands again in 2017 (Infinite Electronics) and 2019 (Microdata Telecom, which also folded in Sweden's Filtronic Wireless AB antenna business), and Kaelus AB was most recently acquired by Baylin Technologies in 2026. Kaelus's tower mounted amplifier (TMA) range remains a widely deployed antenna-line product for reducing uplink noise figure at the antenna, and the enquiry on this page is for a single dual-band TMA unit.

How to read these part numbers

TMA2053F03V2-4 reads as: TMA (tower mounted amplifier), 2053 (model family), with the source description confirming a dual-band 1800/2100MHz unit (DB TMA1800/2100), and an AISG 2.0 control interface for remote monitoring and configuration from a site controller. The trailing suffix (03V2-4) is Kaelus's own variant/revision code.

Ordering notes

Confirm your site controller or OSS supports the AISG 2.0 protocol before ordering — an AISG 2.0 unit will not fully interoperate with an AISG 1.1-only controller for remote monitoring functions, even though RF performance is unaffected. Condition is stated per quotation; this is a refurbished or used unit, not new stock, and availability is confirmed on enquiry. Hardware only: any monitoring software or licensing remains between the buyer and their own network management platform. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will confirm this on the quotation.

Lifecycle and availability

Kaelus continues as an active manufacturer of RF conditioning and PIM test equipment, most recently acquired by Baylin Technologies (Kaelus AB) in 2026 after a series of earlier ownership changes (the Triasx/Smiths Interconnect lineage unified as Kaelus in 2010, then Infinite Electronics in 2017, then Microdata Telecom in 2019). The unit offered on this page is refurbished or used secondary-market stock, not new production.

Equipment condition

New — factory-sealed, supplied through the manufacturer's authorised channel or an authorised distributor, with full manufacturer warranty.

New surplus — unused factory stock, original packaging where available, sourced from decommissioned projects or distributor inventory. Manufacturer warranty may have lapsed; CRS PLUS warranty applies.

Refurbished / tested — previously deployed equipment, cleaned, firmware-checked and functionally tested against the manufacturer's specification before shipment. CRS PLUS warranty applies.

Condition is confirmed in writing on every quotation before you commit to an order.

Warranty

Warranty terms vary by item, by condition and by the supplier the equipment is sourced from. They are stated in writing on the quotation, per line item, before you commit to an order.

Where equipment is supplied new through an authorised channel, the manufacturer's warranty applies and is passed to you.

Send us the part numbers you need and we will confirm warranty terms alongside availability, condition, lead time and price.

Frequently asked questions

Yes. Kaelus continues to manufacture RF conditioning and PIM test equipment. Its ownership has changed several times — most recently Kaelus AB was acquired by Baylin Technologies in 2026 — but the product range and support channel remain active.
