Analog Devices has released new RF and Microwave (MW) switch and attenuator products which have been implemented using an advanced silicon process. These parts benefit from the inherent advantages of silicon technology compared to legacy counterparts using gallium-arsenide (GaAs).
Analog Devices have released the following three new switch products in silicon technology:
HMC1118, a high isolation silicon SPDT nonreflective switch that operates in 9 kHz to 13 GHz. The HMC1118 is optimized for low frequency operation, it has a settling time of 7.5 µs for 0.05 dB margin, excellent isolation of 56 dB at 8 GHz, and a low insertion loss of 0.6 dB at 8.0 GHz. It offers high power handling of 36 dBm through path and 27 dBm terminated path.
HMC8038, a high isolation silicon SPDT nonreflective switch that operates in 0.1 GHz to 6 GHz. The HMC8038 features a high isolation of 60 dB typical, a low insertion loss of 0.8 dB typical, and a fast settling time of 170 ns for 0.1 dB margin. It offers high power handling of 34 dBm through path and 29 dBm terminated path, and high linearity of 34 dBm for 0.1 dB compression point.
HMC7992, a compact silicon SP4T nonreflective switch that operates in 0.1 GHz to 6 GHz. The HMC7992 offers a high isolation of 45 dB typical at 2 GHz, a low insertion loss of 0.6 dB at 2 GHz, and a fast settling time of 320 ns for 0.1 dB margin. It features high power handling of 33 dBm through path and 27 dBm terminated path, and high linearity of 1 dB compression point (P1 dB), with 35 dBm typical.
Analog Devices have released four new digital attenuator products available in silicon technology:
HMC1119, 0.25 dB, LSB, 7-bit and HMC1122, 0.5 dB, LSB, 6-bit silicon digital attenuators (0.1 GHz to 6 GHz). The HMC1119 and HMC1122 are designed for high accuracy and exhibit less than 0.1 dB step error. Both parts have an attenuation range of 30 dB, insertion loss of 1.3 dB, and a typical switching time of around 150 ns. They have a serial control interface with safe-state transition feature.
HMC305S, a 0.5 dB, LSB, 5-bit silicon digital attenuator (0.4 GHz to 7.0 GHz). The HMC305S has an attenuation range of 15.5 dB with insertion loss of 1.1 db at 2 GHz. The part has serial control interface and features glitch-free state transitions.
HMC540S, a 1 dB, LSB, 4-bit silicon digital attenuator (0.1 GHz to 8 GHz). The HMC540S is a wideband, 1 dB step, 4-bit digital attenuator optimized for low insertion of 0.7 dB. The part has excellent linearity of 0.1 dB compression point of 31 dBm. The HMC540S comes in compact 3 mm x 3 mm package and has parallel control.
