The following changes replace the original contents of DCR577:
Para 1.4.2 (Variant Table):
Add new Variant 32 and notes 1 & 2 as follows:
Variant Number: 32 (Note 1)
Nominal attenuation (dB): 0
Att Tolerance (dB)(at DC / DC to 18Ghz/ 18 to 22Ghz): 0.2 / 0.3 / 0.4
Att flatness: same as for Variant 01
VSWR: same as for Variant 01
Max Rated RF Power (W)(PRF): 2 or 5 (Note 2)
Max Weight (g): 5
Note 1: Variant 32 is a DC shunt attenuator that includes a high value series resistance element.
Note 2: PRF =2W for f=DC to 22GHz; PRF =5W for f=5GHz to 22GHZ.
Amend 8th column header to be: Maximum Rated RF Power (W)(PRF)
Para 1.5 (Maximum Ratings table):
For Peak Power, amend Max Rating to be Note 3 (was Note 1)
For RF Power, Peak Power add to the remarks:
Tamb <=+25C
For DC Power replace Tamb =+25C by Tamb <=+25C
For Coupling Nut Torque change remark to Note 4 (was Note 3)
Amend note 1 to read:
1. The maximum rated RF Power is specified in Component Type Variants and Range of Components. The maximum rated DC Power shall be the same value.
amend note 2 to read:
2. RF Power shall be derated against operating temperature as follows:
For Tamb >+25C, derate linearly to 500mW at +125C
Renumber note 3 to be note 4 and change reference to be "(see Physical dimensions)" (was (See Para. 1.6))
Add new note 3:
3. For Variants 01 to 31 the maximum rated Peak Power shall be 100xPRF for f =DC to 22GHz.
For Variant 32 the maximum rated Peak Power shall be 50W for f =5GHz to 22GHz.
Para.2.6.1 (Room Temp Electrical Measurements table)
Add new characteristic as follows:
Characteristics: Series Resistance
Symbols: Rs
Test Methods & Conditions: f=DC, Note 5, Variant 32 only
Limits: 4 min, 10 max
Units: dB
