The HMC183QS24 is a low-cost non-reflective SP8T switch from Hittite Corporation. It is packaged in a 24-lead QSOP and has a frequency range of DC-2.0GHz. The insertion loss is 0.8dB and it features a 3:8 decoder that allows it to be controlled with 3 control lines and a negative bias.
The HMC183QS24 is a GaAs MMIC SP8T non-reflective switch designed for use in antenna diversity, switched filter banks, gain/attenuation selection, and general channel multiplexing applications. It features an integrated 3:8 decoder that requires only three control lines with negative bias to select an RF path, replacing the sixteen control lines typically required by standard GaAs SP8T switches.
| Frequency Range | DC - 2.0 GHz |
|---|---|
| Insertion Loss (1 GHz) | Typical: 0.8 dB |
| Isolation (DC - 2.0 GHz) | Min: 26 dB, Typ: 30 dB |
| Return Loss (RFC) DC - 1.5 GHz | Min: 10 dB, Typ: 14 dB |
| Input Power for 1 dB Compression (50 MHz) | 18 dBm |
| Operating Temperature Range | -40 to +85 °C |
The integrated 3:8 decoder requires only three control lines with negative bias to select an RF path, replacing sixteen control lines normally required by GaAs SP8T switches.
The HMC183QS24 is available in a 24-lead QSOP package.
