Abstract
A K-band (18–26.5 GHz) single-chip reconfigurable and multi-functional RF-MEMS switched dual-LNA MMIC (optimized for lowest/highest possible noise figure/linearity) is presented.
The two MEMS switched low-NF and high-linearity LNA circuit functions present 18.6 dB/9.0 dB, 2.4 dB/3.5 dB and 22 dBm/29 dBm of small-signal gain, noise figure and OIP 3 at 20 GHz, respectively.
The in-band isolation levels of the two switched LNA paths equal 16–20 dB when the MEMS switches are switched on and off.
Compared with two fixed (non-reconfigurable) LNA breakout circuits, the MEMS switched LNA circuit functions show 0.5–1.0 dB higher NF together with similar values of linearity at 15–25 GHz.
