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 Handset
Circuits and 75 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.
