CMD195 DC-20 GHz SPDT Non-reflective Switch Features Functional Block Diagram Positive gain slope B A High isolation 3 4 5 RFC Fast switching speed A B Non-reflective design 2 6 Small die size Description RF1 RF2 1 7 The CMD195 is a broadband non- A B A reflective GaAs MMIC SPDT switch in 10 9 8 die form. The CMD195 covers DC to 20 GHz and offers a low insertion loss of 2 dB and high isolation of 37 dB as well as positive gain slope. The positive gain slope feature allows for several switches to be cascaded together without the need for gain equalization circuitry. The CMD195 die operates using complementary control voltage logic lines of 0/-5 V and requires no bias supply. o Electrical Performance - V = 0/-5 V, T = 25 C, F = 20 GHz ctl A Parameter Min Typ Max Units Frequency Range DC - 20 GHz Insertion Loss 2 dB Isolation 41 dB Return Loss - On State 17 dB Return Loss RF1, RF2 - Off State 20 dB Input P1dB 25 dBm Switching Characteristics tRISE, tFALL (10/90% RF) 1.8 ns tON, tOFF (50% CTL to 10/90% RF) 11/4 ns ver 1.6 0320 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.comCMD195 DC-20 GHz SPDT Non-reflective Switch Specifications Absolute Maximum Ratings Control Voltages Parameter Rating State Bias Condition RF Input Power +27 dBm Low 0 to -0.5V 1 uA Typ High -3V 1 uA Typ to -7V 6 uA Typ Control Voltage Range (A,B) +0.5V to -7.5V Channel Temperature, Tch 150 C Operating Temperature -40 to 85 C Truth Table Storage Temperature -55 to 150 C Control Input Signal Path State Power Dissipation, Pdiss A B RFC to RF1 RFC to RF2 Thermal Resistance,Q JC High Low On Off Exceeding any one or combination of the maximum ratings may cause permanent damage to the device.
