com SiGe, High-Linearity, 2300MHz to 4000MHz Downconversion Mixer with LO Buffer General Description The MAX19998 single, high-linearity downconversion mixer provides 8.
7dB of conversion gain, +24.
3dBm input IP3, +11.
3dBm 1dB input compression point, and a noise figure of 9.
7dB for 2300MHz to 4000MHz WiMAXK, LTE, and MMDS receiver applications.
With an ultra-wide LO 2600MHz to 4300MHz frequency range, the MAX19998 can be used in either low-side or high-side LO injection architectures for virtually all 2.
5GHz and 3.
5GHz applications.
For a 2.
5GHz variant tuned specifically for high-side injection, refer to the MAX19996A.
In addition to offering excellent linearity and noise performance, the MAX19998 also yields a high level of component integration.
This device includes a doublebalanced passive mixer core, an IF amplifier, and an LO buffer.
On-chip baluns are also integrated to allow for single-ended RF and LO inputs.
The MAX19998 requires a nominal LO drive of 0dBm, and supply current is typically 230mA at VCC = 5.
0V or 150mA at VCC = 3.
3V.
The MAX19998 is pin compatible with the MAX19996/ MAX19996A 2000MHz to 3900MHz mixer family.
The device is also pin similar with the MAX9984/MAX9986/ MAX9986A 400MHz to 1000MHz mixers and the MAX9993/MAX9994/MAX9996 1700MHz to 2200MHz mixers, making this entire family of downconverters ideal for applications where a common PCB layout is used for multiple frequency bands.
The MAX19998 is available in a compact, 5mm x 5mm, 20-pin thin QFN with an exposed pad.
Electrical performance is guaranteed over the extended -40NC to +85NC temperature range.
