Abstract
An apparatus includes a package and a beam former circuit. The package may be configured to be mounted on an antenna array at a center of four antenna elements. The beam former circuit may (i) be disposed in the package, (ii) have a plurality of ports, (iii) be configured to generate a plurality of radio-frequency signals in the ports while in a transmit mode and (iv) be configured to receive the radio-frequency signals at the ports while in a receive mode. A plurality of ground bumps may be disposed between the beam former circuit and the package. The ground bumps may be positioned to bracket each port. Each ground bump may be electrically connected to a signal ground to create a radio-frequency shielding between neighboring ports.
