This 2-port component provides a:
- Match to resistance R₁ at port 1 when port 2 is terminated in R₂
- Match to R₂ at port 2 when port 1 is terminated in R₁
- Desired attenuation, DB
Resistive networks can achieve simultaneous match at input and output if the insertion loss factor A exceeds a minimum value given by

where:
DB_MIN = 10 × log₁₀(A_MIN)
