6 / 8 page CHM2378a W-band Dual Channel Mixer Ref. DSCHM2378a6354 - 20 Dec 06 6/8 Specifications subject to change without notice Route Départementale 128, B.P.46 - 91401 ORSAY Cedex - FRANCE Tel.: +33 (0) 1 69 33 03 08 - Fax: +33 (0) 1 69 33 03 09 Typical Assembly Configuration L_lo µ-strip line L_rf2 µ-strip line L_rf1 µ-strip line R_bias C1 +V IF1 120pF R_bias C2 +V IF2 120pF This drawing shows an example of assembly configuration. The bias and IF inter- connections are according to the example given in the previous chapter. For the RF pads the equivalent wire bonding inductance (diameter=25µm) have to be according to the following recommendation. Port Equivalent inductance (nH) Approximative wire length (mm) LO (2) L_lo= 0.26 0.33 RF1 (10) L_rf1 = 0.26 0.33 RF2 (13) L_rf2 = 0.26 0.33 For a micro-strip configuration a hole in the substrate is recommended for chip assembly. As the connections at 77GHz (between MMIC and MMIC or between MMIC and external substrate) are critical, the transition matching network is split into two parts: one on MMIC and one on the external substrate. This choice allows doing both kinds of connections. |
