The AMF-3F-26004000-33-8P from MITEQ is a recent addition to its family of low-noise, wideband coaxial LNAs in the 26 to 40 GHz band. It has over 18 dB of gain in a housing that is only 11,4 mm long and 19 mm wide without the field-replaceable 2,93 mm connectors.
Gain flatness is a maximum of ±2,5 dB. The device has a maximum noise figure of 3,3 dB in the full band, though the typical value is 3,0 dB. It operates from -40°C to +75°C, has an output P1dB of minimum +8 dBm, output IP3 of typically +16 dBm and a current draw of maximum 200 mA from a single +15 V d.c. supply.
Port VSWR is typically less than 2:5 for both input and output. The aluminium alloy housing provides excellent thermal performance in addition to being very small and light. An hermetic version is available, as are wider frequency and higher gain options.
