What are the key features of MA4P1250-1072T?
- Wideband frequency range of 0.1 MHz to 1500 MHz covering HF, VHF, UHF, and L-band RF switching and attenuation
- Low junction capacitance of 0.9 pF nominal (1.5 pF max) at reverse bias enabling high-frequency signal isolation above 1 GHz
- High reverse breakdown voltage of 100 V minimum and 500 Vdc isolation for high-power attenuator circuits
What is MA4P1250-1072T used for?
The MA4P1250-1072T is designed for RF attenuators, transmit/receive switches, and phase shifters in communications equipment operating between 0.1 MHz and 1500 MHz. Its low 0.9 pF capacitance and low distortion characteristics make it suitable for linear RF control circuits in military radio, satellite ground terminals, and cellular base station antenna switching networks. The isolated chip package allows flexible circuit integration in hybrid microwave assemblies and RF module designs requiring high voltage isolation up to 500 Vdc.

Frequently Asked Questions
What is the junction capacitance of MA4P1250-1072T and how does it affect high-frequency switching performance?
The MA4P1250-1072T has a nominal junction capacitance of 0.9 pF and a maximum of 1.5 pF at reverse bias, which limits parasitic feedthrough to under -20 dB isolation at 1500 MHz, making it effective for RF switching in L-band and UHF attenuator circuits.
For a VHF attenuator design, how does the MA4P1250-1072T handle linearity requirements?
The MA4P1250-1072T is specifically rated for low distortion attenuator applications, with its intrinsic I-layer providing resistive control from forward bias currents of 1 mA to 20 mA across the 100 MHz to 500 MHz VHF band while maintaining third-order intercept (IP3) performance adequate for communications receivers.
What reverse voltage rating does MA4P1250-1072T have and which high-power switching applications does this enable?
The MA4P1250-1072T has a minimum reverse breakdown voltage of 100 V and an isolation voltage of 500 Vdc, making it suitable for high-power transmit/receive switches in radar, HF amplifiers, and military tactical radios that switch RF signals at power levels up to 10 W CW.
How does the isolated chip package of MA4P1250-1072T benefit microwave hybrid circuit integration?
The CASE 1072 isolated chip package of MA4P1250-1072T has no conductive connection between the die and the package body, allowing the designer to mount the diode on a microstrip circuit substrate with independent DC bias without ground shorting, enabling flexible T-network or Pi-network attenuator topologies at 0.1 MHz to 1500 MHz.
