Keysight TC221 50 GHz Frequency Doubler 1GC1-8038 Data Sheet Features Conversion Efficiency: 12 db Typical 1/2 and 3/2 spurs: 15 dbc Typical Broad Bandwidth, 20 50 GHz Output Frequency
Introduction The TC221 is a passive diode frequency doubler. It is specified to operate with a 20 50 GHz output frequency. Conversion efficiency is usually around 12 db. The device has low 1/2 and 3/2 spurious output, typically 15 dbc or better. The doubler can be biased through on chip resistors to allow operation at low input levels. Up to 22 dbm at the input can be accommodated. On chip DC blocking capacitors are included at the input and output.

No bias means bias + open, bias open) Applications The TC221 frequency doubler is designed for use in microwave instrumentation source applications. Operation The TC221 is a passive diode doubler, with + and DC bias pads included to optimize performance at low input power levels. Bias can be applied through either the + or bias pad or both, with the other pad either grounded or open. The optimum bias will depend on frequency and input power level, and must be empirically optimized for each application. DC blocking capacitors have been included at the input and output of the device for ease of interface to other devices. The device should be mounted using epoxy or solder to a metal case with thermal conductivity equal to, or better than, aluminum, and the case temperature should not exceed 85 C. This will keep the diode junctions at or below 130 C for an input power of 22 dbm, and will keep the rectified diode currents well within acceptable limits for reliable operation.
04 Keysight TC221 50 GHz Frequency Doubler - Data Sheet Assembly Techniques Epoxy die attach using conductive epoxy or solder die attach using a fluxless AuSu solder preform can be used for assembly. Gold thermosonic wedge bonding with 0.7 mil diameter Au wire is recommended for all bonds. Tool force should be 22 ± 1 gram, stage temperature should be 150 ± 2 C, and ultrasonic power and duration should be 64 ± 1 db and 76 ± 8 msec, respectively. The bonding pad and chip backside metallization is gold. GaAs MMICs are ESD sensitive. ESD preventive measures must be employed in all aspects of storage, handling, and assembly. MMIC ESD precautions, handling considerations, die attach and bonding methods are critical factors in successful GaAs MMIC performance and reliability. Keysight Technologies Application Note #54 (5991-3484EN), GaAs MMIC ESD, Die Attach and Bonding Guidelines provides basic information on these subjects. Figure 1.
