Taoglas, a trusted provider of antennas and IoT components, has expanded its TFM series of multi-band GNSS front-end modules.
Building upon the existing product range, the expanded series offers design engineers more options for simplifying and accelerating product development for high-precision GNSS applications.
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.
"Using TFM modules typically saves designers at least six months of development time compared to designing active circuitry on the PCB themselves,” said Taoglas Chief Executive Officer, Dermot O’Shea. “It not only speeds things up and enables them to focus on the rest of their design, but because of our many years of experience designing such circuits for our own antennas, you know you are getting best in class and can be confident in the reliability and accuracy of your GNSS data."
