Description
The HPND-4028 and 4038 beam lead PIN diodes are designed for low capacitance, low resistance, and fast switching at microwave frequencies. These characteristics are achieved at low bias levels for minimal power consumption. Advanced processing techniques ensure uniform and consistent electrical performance, allowing guaranteed capacitance windows. This translates to improved performance in phased array applications.

FEATUREs
• Low Capacitance
    0.025 pF Maximum at 1 MHz Guaranteed Min./Max.
• Fast Switching
    2.0 nsec
• Low Resistance at Low Bias
    1.5 Ω at IF = 10 mA (Typical)
• Rugged Construction
    Typical 10 Gram Lead Pull
• Silicon Nitride Passivation

APPLICATIONs
    These beam lead PIN diodes are designed for use in stripline, coplanar waveguide, or microstrip circuits. Applications include phase shifting and switching. The guaranteed capacitance windows ensure uniform performance in phased array radar. The low capacitance makes them ideal for circuits requiring high isolation in the series configuration. These devices have been fully characterized and S-parameters have been provided.
