Alpha's product line of silicon Schottky diode chips are intended for use as detector and mixer devices in hybrid integrated circuits at frequencies from below 100 MHz to higher than 40 GHz. Alpha's "Universal Chip" design features a 4 mil diameter bond pad that is offset from the semiconductor junction preventing damage to the active junction as a result of wire bonding.
As power-sensing detectors, these Schottky diode chips all have the same voltage sensitivity so long as the outpu video impedance is much higher than the video resistance of the diode. Figure 1 shows the expected detected voltage sensitivity as a function of RF source impedance in an untuned circuit. Note that sensitivity is substantially increased by transforming the source impedance from 50 Ω to higher values. Maximum sensitivity occurs when the source impedance equals the video resistance.
In a detector circuit operating at zero bias, depending on the video load impedance, a ZBD device with RV less than 10 kΩ may be more sensitive than a low barrier diode with RV greater than 100 kΩ. Applying forward bias reduces the diode video resistance as shown in Figure 2. Lower video resistance also increases the video bandwidth but does not increase voltage sensitivity, as shown in Figure 3. Biased Schottky diodes have better temperature stability and also may be used in temperature compensated detector circuits. P-type Schottky diodes generate lower 1/F noise and are preferred for Doppler mixers and biased detector applications.The bond pad for the P-type Schottky diode is the cathode.N-type Schottky diodes have lower parasitic resistance, RS, and will perform with lower conversion loss in mixer circuits. The bond pad for the N-type Schottky diode is the anode.
