!

C3 produces a peak that is centered approximately 300 MHz above the lowest forward
frequency and varied in amplitude by R3. This adjustment provides more mid-band
alignment flexibility.

!

C6 adjusts for maximum gain at Fmax (870 MHz).

!

C7 and R8 adjust for the flattest response in the mid- to upper portion of the band.

!

C8 adjusts for the flattest response in the low to mid-range of the band.

L4, on the bottom of the LDR board, may slightly tune the upper portion of the response.
Excessive spreading of L4 will increase insertion loss.

Figure 3-3 illustrates the LDR/*/III:
