Note: The capacitor value for C1-C6 shown in the stan-
dard Application Circuit as 0.1 uF will result in excellent
wideband small signal performance from 200 kHz to
500 MHz. Small signal operation to frequencies lower
than 200 kHz is possible through the proper selection of
capacitors C1-C6. Contact Hittite Applications Group for
proper selection of C1-C6 values for frequencies lower
than 200 kHz.

FREQUENCY (MHz)
Note: The 0.1 dB Input Compression Point degrades for
low frequency operation. Typical 0.1 dB Input Compres-
sion Point at 60 MHz is +27 dBm tapering to +5 dBm at
250 kHz. The typical 0.1 dB Compression Point holds
constant at +5 dBm for frequencies lower than 250 kHz.
Hittite recommends that Absolute Maximum Input Power
Levels be maintained to less than the 0.1 dB Compression
point for reliable operation of the HMC624LFLP4E.
