Silicon, SPDT Switch, Nonreflective, 100 MHz to 13 GHz

The ADRF5019 is a nonreflective, single pole, double throw (SPDT) RF switch manufactured in a silicon process.

The ADRF5019 operates from 100 MHz to 13 GHz with better than 0.8 dB insertion loss and 45 dB of isolation at 8 GHz. The ADRF5019 has a nonreflective design, and the RF ports are internally terminated to 50 Ω.

The ADRF5019 switch requires a dual supply voltage of +3.3 V and −2.5 V and positive control voltage inputs. This switch employs complementary metal-oxide semiconductor (CMOS)-compatible and low voltage transistor transistor logic (LVTTL)-compatible controls.

The ADRF5019 can also operate with a single positive supply voltage (VDD) applied. The negative supply voltage (VSS) is tied to ground. Even in single-supply operation mode, the ADRF5019 can cover the 100 MHz to 13 GHz operating frequency and maintain good power handling performance. See the Applications Information section for more details.

The ADRF5019 is pin-compatible with the HMC1118, the low frequency cutoff version, which operates from 9 kHz to 13.0 GHz.

The ADRF5019 comes in a 16-lead, lead frame chip scale package (LFCSP) and operates from −40°C to +105°C.
