Abstract :
This paper discusses the design, simulation and measurement results of a single-ended to differential Low Noise Amplifier (LNA) for 24 GHz short range car radar applications in a production 0.25 mum SiGe:C-BiCMOS technology [1]. The input and two single-ended outputs are designed for 50 Omega impedance. The LNA achieves a measured 13.2 dB gain and 4.2dB noise figure at 24 GHz. Simulations and measurements are in close agreement. The achieved gain and noise figure are as good as for an earlier reported fully single-ended LNA [2]. No balun is required. The 0.55 x 0.60 mm IC dissipates 40 mW from a 3.3 V supply.
