(3) LCR Quad Tank
NOTES: 1. Saw Filter – Siemens part number Y6970M(5 pin SIP plastic package).
2. An LCR filter reduces the broadband noise in the IF; ceramic filters may be used for data rates under 500 kHz. 4.0 dB insertion loss filters
optimize the linearity of RSSI.
3. The quadrature tank components are chosen to optimize linearity of the recovered signal while maintaining adequate recovered
signal level. 1.5 µH 7.0 mm variable shielded inductor: Toko part # 292SNS–T1373Z. The shunt resistor is approximately equal to
Q(2πfL), where Q ∼ 18 (3.0 dB BW = 600 kHz).
4. The local oscillator circuit utilizes a 122.7 MHz, 5th overtone, series resonant crystal specified with a frequency tolerance of 25 PPM, ESR
of 120 Ω max. The oscillator configuration is an emitter coupled butler.
5. The 95 NH (Nominal) inductor is a 7.0 mm variable shielded inductor: Coilcraft part # 150–04J08S or equivalent.
6. 0.68 µH axial lead chokes (molded inductor ): Coilcraft part # 90–11.
7. To enable the IC, Pin 25 is taken to VEE. The external pull down resistor at Pin 29 could be linked to the enable function; otherwise if it is
taken to VEE as shown, it will keep the oscillator biased at about 500 µA depending on the VCC level.
8. The other resistors and capacitors are surface mount components.
