The SKY16601-555LF is a fully integrated PIN diode lowthreshold limiter module in a surface-mount package. It is designed for use as a passive receiver protector in wireless or other RF systems for frequencies up to 6 GHz. It features lowinsertion loss and low distortion in a single MLP package. The SKY16601-555LF module is comprised of a PIN limiter diode, an RF choke inductor, and 2 DC blocking caps at the RF ports in a 2-lead MLP package. The small package design reduces printed circuit board area. The module can operate over the temperature range of –40 ˚C to +85 ˚C. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

The SKY16601-555LF is a single-stage limiter module, comprised of a shunt-connected PIN diode that biases itself in the presence of large signals. The PIN diode performs the dual functions of rectifying the incoming RF signal and then using the rectified current to bias itself to a low effective series resistance. An inductor completes the loop for the bias current flow while presenting a high impedance path to RF. The SKY16601-555LF includes input/output DC blocking capacitors needed for most applications. Typical Performance Characteristics (TOP=25°C, Characteristic Impedance = 50 Ω) Typical performance characteristics are illustrated in Figures 3 and 4. Figures 5 and 6 show the power derating curves for the limiter module. In Figure 5, the temperature is referenced to the bottom of the MLP package. The power derating curve with the temperature referenced to the bottom of the printed circuit board is shown in Figure 6. 5 0 –5 Insertion Loss (dB) –10 –15 –20 –25 –5 –10 –15 500 MHz 900 MHz 2000 MHz –20 –30 2500 MHz S21 S11 –35 3500 MHz –25 –40 0 2 4 6 8 Y0661 |S–Parameter| (dB) 0 0 5 10 10 Frequency (GHz) 20 25 30 40 45 40 Maximum CW Input Power (Watts) 40 35 30 25 20 15 10 5 35 30 25 20 15 10 5 0 0 25 45 65 85 105 125 145 165 Bottom of Package Leadframe Temperature (°°C) Figure 5.
