HMC199AMS8E

HMC199AMS8E is a low-cost general purpose dual SPDT GaAs “bypass” switch covering DC to 2.5GHz. These four-RF-port components integrate two SPDT switches and a through line onto a single IC. The designs provide low insertion loss of less than 0.5dB while switching passive or active external circuit components in and out of the signal path. Port to port isolations are typically 25 to 30dB. On-chip circuitry enables positive voltage control operation at very low DC currents with control inputs compatible with CMOS and most TTL logic families. Applications include LNA or filter bypass switching and single bit attenuator switching. It is used in applications such as cellular, ISM base stations, PCS etc.

• Insertion loss is 0.3dB typical at (DC - 1GHz, TA = +25°C, Vctl = 0/+5Vdc)
• Isolation is 25dB typical at (DC - 2GHz, TA = +25°C, Vctl = 0/+5Vdc)
• Return loss (on state, any port) is 30dB typical at (DC - 2GHz, TA = +25°C, Vctl = 0/+5Vdc)
• Input power for 1dB compression is 28dBm typical at (0.5GHz to 2GHz, TA = +25°C, Vctl = 0/+5Vdc)
• Input third order intercept is 55dBm typical at (0.5GHz to 2GHz,TA = +25°C, Vctl = 0/+5Vdc)
• Switching characteristics is 20ns typical at (DC - 2.5GHz, TA = +25°C, Vctl = 0/+5Vdc)
• Operating temperature is -40°C to +85°C
• Package style is ultra small MSOP8
