Abstract

A K-band transceiver (TRX) front-end in 0.15 μ mGaN with TRX switch functionality is presented. In a compact area of 3mm2, the chip contains a PA and LNA while also realizing a transmit/receive (T/R) switch functionality by the aid of an asymmetric edge coupler, without having an explicit switch in the TRX signal path. In TX mode, the front-end achieves a saturated output power (P s a t ) of 27. 7dBm with a 26.8% saturated PAE under a continuous wave (CW) input signal. The RX path achieves a 4. 7dB noise figure (NF). The compact MMIC can be used in phased array transceivers.
