Description
M/A-COM's MA4P274-1225 is a wideband, lower insertion
loss, high IP3, Quad PIN Diode π Attenuator in a low-cost,
surface mount SOT-25 package. Four PIN Diodes in one
package reduce design parasitics and improve circuit
density.
Applications
These PIN Diode Attenuators perform well where RF
Signal Amplitude Control is required in 50 Ω Handset
Circuits and 75 Ω Broadband CATV Systems. Exceptional
Insertion Loss, Attenuation Range, and IP3 at <10 mA bias
make these devices suitable for better power level control in
RF Amplifiers.
