Application Notes for RF Switches
The Models F9180 and F9180W SP8T switches operate over a frequency range of 1 to 18 GHz. They are low-cost state-of-the-art, high isolation, low Insertion loss units. For the Model F9180, the reflective design, Insertion loss varies from 1.5 dB at 1 GHz to 4.4 dB at 18 GHz. The corresponding values for the Model F9180W, the non-reflective design, are 2.0 dB and 4.8 dB, respectively. Isolation varies from 65 dB at 1 GHz to 60 dB at 18 GHz, for Model F9180 and 55 dB for Model F9180W. The VSWR limit for both designs ranges from 1.7 to 2.0, depending on frequency. These units switch in under 250 nanoseconds. They operate over temperature ranges as wide as -54°C to +110°C and withstand RF power levels as high as 75 watts peak, 1 watt average.
Each model weighs 8.5 ounces and measures 4.65 x 1.5 x 0.75″. They are powered by +5V DC and -12 to -15V DC (standard) or by ±5V DC (Option 11). Individual port TTL logic control and power supply connections are made by means of a DA15P connector.
