Charmille - Parc SILIC - 10, Avenue du Québec - 91140 VILLEBON-SUR-YVETTE - France Tel.: +33 (0) 1 69 86 32 00 - Fax: +33 (0) 1 69 86 34 34 Recommended chip assembly The design of the circuit integrates a half ribbon (75µm wide) connection at the input and the output of the MMIC amplifier compliant with a 50 Ohm line on GaAs MMIC. Circuits having to be as close as possible to each other, the ribbon length must be reduced to the achievable minimum (160µm gap between two chips is considered) and the loop height must also be the smallest realizable (80µm). A second solution is the use of double wires (Ø 25µm). In this case, a minimum of two wires and the same chip to chip distance than ribbon solution are necessary to reduce the inductance effect. Nevertheless, simulations have demonstrated an improvement of RF performance for E-band frequency range with the use of ribbon connection instead of wire. Regarding the connection of the DC pads, a 25µm wedge bonding is preferred. 120pF 120pF 120pF 160µm Gap 75µm Ribbon To VG Power supply 10nF 10nF Ribbon(W75µm,length≈330µm ) MMIC CHA2080 Hyper access 160µm Hyper access 85µm |
