About
The KKa-LNA-1929 is a three-stage GaAs pHEMT MMIC low noise amplifier covering K-band (17-21 GHz) and Ka-band (27-31 GHz) simultaneously, making it a dual-band solution for satellite receive chain integration. It delivers 16-24 dB gain (typically 20 dB) with a noise figure of 2.5-3.2 dB, providing the low-noise amplification required at the front end of Ka-band satellite receivers.
With input return loss of 8-20 dB and output return loss of 5.5-10 dB, the MMIC is designed for 50 Ohm system integration and operates from a 4-6 V supply drawing 41-132 mA. The bare die form factor (4.38 x 2.00 x 0.10 mm, gold-plated backside) enables integration into multi-chip modules, hybrid circuits, and compact satellite payload assemblies where minimum size is paramount.
The KKa-LNA-1929 is part of Arralis’ Leonis chipset family, designed specifically for satellite communications applications including high-speed LEO data downlinks, IoT satellite constellation receivers, and security/imaging systems. Its operating temperature range of -40C to +85C and storage range of -65C to +150C make it qualified for both commercial and space-grade applications.
