Note) *1: IQ signal amplitude: 0.18 V[p-p] (both phases), DC bias: 1.5 V, π/4 QPSK-modulated [0000] continuous wave input.
PO1 output frequency: 889.002625 MHz, PO2 output frequency: 960.002625 Hz, Pmin output frequency: 950.002625 MHz
An output level be measured by a spectrum analyzer.
Setting of a spectrum analyzer: SPAN = 20 kHz, RBW = 300 Hz, VBW = 30 Hz, ST = 5 s
(When inputting π/4 QPSK-modulated [0000] continuous wave as IQ signal, the frequency for PO1 , PO2 and Pmin becomes
Lo frequency + IQ signal frequency, which leads to the above value.)
Lo input level is the setting value of a signal source (output impedance 50 Ω).

Request for your special attention and precautions in using the technical information
and semiconductors described in this material
(1) An export permit needs to be obtained from the competent authorities of the Japanese Government if any of the products or technologies described in this material and controlled under the
"Foreign Exchange and Foreign Trade Law" is to be exported or taken out of Japan.
(2) The technical information described in this material is limited to showing representative characteristics and applied circuit examples of the products. It does not constitute the warranting of industrial
property, the granting of relative rights, or the granting of any license.
(3) The products described in this material are intended to be used for standard applications or general electronic equipment (such as office equipment, communications equipment, measuring instruments and household appliances).
Consult our sales staff in advance for information on the following applications:
• Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment,
combustion equipment, life support systems and safety devices) in which exceptional quality and
reliability are required, or if the failure or malfunction of the products may directly jeopardize life or
harm the human body.
• Any applications other than the standard applications intended.
