Product speciﬁcation

9 V VHF, hyperband and UHF

mixer/oscillator for TV and VCR 3-band tuners

TDA5630;

TDA5631

Fig.4 Gain measurement in band A.

Zin (AIN) >> 50 Ω => Vi =2 × Vmeas.

Vi =Vmeas + 6 dB.

Vo =V’meas + 15.4 dB (transformer ratio N1/N2 = 5 and transformer loss).

Gv = 20 log (Vo/Vi) = 20 log (V’meas/Vmeas) + 9.4 dB.

Fig.5 Input circuit for optimum noise figure in band A.

(a) For fRF = 50 MHz:

mixer A frequency response measured = 57 MHz, loss = 0 dB

image suppression = 16 dB

C1 = 9 pF

C2 =15pF

L1 = 7 turns (diam. = 5.5 mm, wire diam. = 0.5 mm)

l1 = semi rigid cable (RIM): 5 cm long

(semi rigid cable (RIM); 33 dB/100 m; 50

Ω; 96 pF/m).

(b) For fRF = 180 MHz:

mixer A frequency response measured = 150.3 MHz, loss = 1.3 dB

image suppression = 13 dB

C3 = 5 pF

C4 =25pF

l2 = semi rigid cable (RIM): 30 cm long

l3 = semi rigid cable (RIM): 5 cm long

(semi rigid cable (RIM); 33 dB/100 m; 50
