TFM series of multi-band GNSS front-end modules.

TFM modules comprise a two-stage cascaded filter and low noise amplifier (LNA) topology encapsulated within a shielded, robust, compact, low-profile surface mount package. This design ensures streamlined integration with any multi-band antenna or GNSS receiver, acting as a bridge between the antenna and RF module to facilitate the addition of active electronics to GNSS designs.

The TFM series simplifies integration by combining impedance matching, filters, and low noise amplifiers (LNAs) into a single package. The integrated pre-filters attenuate out-of-band signals, while the LNAs ensure an optimal noise figure across the entire signal chain. Furthermore, high-gain architecture, featuring cascaded LNAs with pre-filters and optimized impedance matching, provides at least 25 dB gain to the GNSS receiver. The 1 dB compression points of the modules are -31 dBm or better, depending on the model and frequency. All TFM modules operate from a DC input voltage of 1.8 to 5.5 VDC, providing maximum design flexibility. The compact footprint and low-profile design, housed in a shielded, surface mount package measuring from 15 mm x 15 mm x 2.7 mm, conserves space without the need for external components.
