CXG1189UR is a high power SPDT switch MMIC, which can be used in GSM, UMTS dual mode mobile phones and other wireless communication systems. Its main features include low insertion loss, low harmonics, and small packages.
The CXG1189UR is a high‑power SPDT (Single Pole Dual Throw) MMIC switch designed for wireless communication systems such as GSM and UMTS dual‑mode handsets. It is fabricated with Sony's JPHEMT process to achieve low insertion loss and reduced harmonic levels.
Key specifications include low insertion loss (0.2 dB @ 900 MHz), high output power (up to 37 dBm in the 824‑915 MHz band), and a compact 12‑pin UQFN package. The document also provides recommended external components, bias conditions, and mechanical drawing details. This manual is written in Japanese.
| Insertion loss @ 900 MHz | 0.2 dB |
|---|---|
| Insertion loss @ 1.8 GHz | 0.25 dB |
| Maximum output power (824‑915 MHz) | 37 dBm |
| Operating temperature range | -35 °C to +85 °C |
| Storage temperature range | -60 °C to +150 °C |
| Package type | 12‑pin UQFN |
| Control voltage (Vctl high) range | 2.6 V – 3.6 V |
The recommended resistor (Rctl) is a kΩ value (ktQ) to improve electro‑static strength.
A 100 pF capacitor (Cbypass) is recommended for DC line filtering.
The package material is epoxy resin.
