SILICON PIN DIODES
How to specify a PIN diode
HOW TO SPECIFY A PIN DIODE ?
To obtain the PIN diodes best suited for a specific application, consider the following:
www.DataSheet41U. .coAmpplication
• switch
• attenuator
• limiter
2. Frequency and bandwidth requirements
3. Power characteristics
• peak
• average
• pulse duration and duty cycle
4. Switching time
5. Bias conditions
• forward
• reverse
6. Circuit impedance
7. Shunt or series assembly
8. Maximum loss expected
9. Minimum isolation needed
10. VSWR and distortion requirements
11. Power applied to the diode
• forward biased
• reverse biased
• during switching
12.Static characteristics
• applicable voltage: VR
• total capacitance: CT
(in space charge)
• forward series resistance: RSF
• carrier lifetime τl
• thermal resistance: Rth
13. Mechanical and packaging constraints

SILICON PIN DIODES
Low cost square ceramic package PIN diodes
Applications
TEMEX square ceramic diodes are particularly suitable for high volume tape and reel assembly.
Several values of total capacitance are available, together with a low forward series resistance. These
components are designed to meet the low distortion specification required by all the mobile radio
applications. Due to the specific design, these devices offer low loss and low thermal resistance
performance and are characterized for high power handling. The electrical properties are ideal for use
in antenna switches, filters, phase shifters, in all mobile radio applications from few MHz to GHz
frequencies.
