Technology*	Order	Size (mm $^{2}$ )	$Δ$ f $_{0}$ (GHz)	FBW (%)	IL $_{\min}$ (dB)	RL (dB)
CNC⁶⁷	5	$\approx$ 13 $\times$ 8	130–134/151.5–155.5	4.30	0.5	20
DMLS⁶⁷	5	$\approx$ 13 $\times$ 8	130–134/151.5–155.5	4.30	1.35	8
SMW⁶⁸	6	9.4 $\times$ 2	130–134	5	1.2	20
LTCC⁶⁹	4	3.32 $\times$ 2.37	148.7–150.7	1.30	5.5	10
