The ICs are arranged in two or more subsets of one or more ICs in each subset, where an individual IC belongs to only one subset, different subsets are in different layers with respect to the antenna unit support, and an average pitch of projections of all of the ICs onto a plane parallel to the antenna unit support is substantially equal to, or smaller, than an average pitch of the antenna units. When an average width of the ICs is larger than the average pitch of the antenna units, arranging the ICs in two or more subsets in different layers means that at least one of the ICs of one subset partially overlaps with at least one of the ICs of another subset.

Abstract: A transmit receive switch (TRSW) system is disclosed. The system has a transmission line, a transformer based matching network, a shunt switch, an amplifier and circuitry. The transmission line is connected to an antenna port. The transformer based matching network is connected to the transmission line and has a first coil and a second coil, wherein the second coil is connected to the transmission line. The amplifier can be configured as a shunt switch when inactive. The shunt switch, including the amplifier configured as the shunt switch, can be connected to the first coil of the transformer based matching network. The circuitry is configured to cause the shunt switch to be ON during an inactive mode and create a short across the first coil. Combined, the length of transmission line needed to complete the impedance transformation is reduced, thereby lowering the overall insertion loss of the transmit/receive switch.
