CHU2277A RoHS COMPLIANT W-band Multifunction : Multiplier / MPA GaAs Monolithic Microwave IC Description The CHU2277A is a W-band monolithic multifunction which integrates a frequency multiplier, a four-stage amplifier and a power divider. The frequency multiplier is based on an active transistor and allows to operate at low input level with a reduced power consumption. This chip provides two outputs at 77GHz, the main one is for the transmission path and the auxiliary one for the receiving mixer (s) LO signal. All the active devices are internally self biased. This chip is compatible with automatic equipment for assembly. The circuit is manufactured with the P-HEMT process : 0.15m gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form. +V -V OUT1 IN x2 OUT2 W-band multifunction block-diagram 20 18 Output power (dBm) 16 14 12 10 8 6 4 2 0 75 75,5 76 76,5 77 77,5 78 78,5 79 OUT1 Main Features n n n n n n n n n n n Wide operating frequency range Low input power : 5dBm typical High output power (OUT1) Auxiliary output power (OUT2) Low AM noise High temperature range On-chip self biasing Automatic assembly oriented Low DC power consumption BCB layer protection Chip size : 4.65 x 1.6 x 0.1mm OUT2 Output frequency (GHz) Typical output power characteristic Pin = 7dBm (on wafer measurement) Main Characteristics Tamb = +25C Symbol F_in F_out P_out1 P_out2 Input frequency Output frequency Main output power Auxiliary output power Parameter Min 38 76 Typ Max 38.5 77 Unit GHz GHz dBm dBm 13 10 ESD Protections : Electrostatic discharge sensitive device observe handling precautions !

All the transistors are internally self biased. An external capacitor is recommended for the positive and negative supply voltages. For the RF pads the equivalent wire bonding inductance (diameter=25m) have to be according to the following recommendation. Port IN (2) OUT1 (5) OUT2 (8) Equivalent inductance (nH) L_in = 0.32 L_out1 = 0.32 L_out2 = 0.32 Wire length (mm) (1) 0.4 0.4 0.4 (1) This value is the total length including the necessary loop from pad to pad. For a micro-strip configuration a hole in the substrate is necessary for chip assembly. Ref.

This choice allows to do, for OUT2 port, a direct connection between MMICs. For a connection to an external substrate a network is proposed on soft substrate for OUT1 and OUT2 ports. The following drawings gives the dimensions for a DUROID substrate (thickness=0.127mm, r=2.2). Bonding area Proposed matching network for a 50 transition between OUT1 and a strip line on DUROID substrate Bonding area Proposed matching network for a 50 transition between OUT2 and a strip line on DUROID substrate.
