LTC5598IUF LINER [Linear Technology], LTC5598IUF Datasheet - Page 4

• Manufacturer Part Number: LTC5598IUF
• Description: 5MHz to 1600MHz High Linearity Direct Quadrature Modulator
• Manufacturer: LINER [Linear Technology]

LTC5598
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC5598 is guaranteed functional over the operating
temperature range –40ºC to 85ºC.
Note 3: At 6MHz offset from the LO signal frequency. 100nF between BBPI
and BBMI, 100nF between BBPQ and BBMQ.
Note 4: Baseband is driven by 2MHz and 2.1MHz tones with 1V
two-tone signals at each I or Q input (0.5V
Note 5: IM2 is measured at LO frequency – 4.1MHz.

Note 6: IM3 is measured at LO frequency – 1.9 MHz and LO frequency
– 2.2MHz.
Note 7: Amplitude average of the characterization data set without image
or LO feedthrough nulling (unadjusted).
Note 8: RF power is within 10% of fi nal value.
Note 9: RF power is at least 30dB lower than in the ON state.
Note 10: External coupling capacitors at pins LOP , LOM and RF are 100pF
each.
Note 11: Tests are performed as shown in the confi guration of Figure 10.
The LO power is applied to J3 while J5 is terminated with 50Ω to ground
for single-ended LO drive.
