Notes
1. The voltage gain Gv is defined as the ratio between the single-ended output voltage and the differential input voltage
with
a 150 Ω
output load:

2. The tilt is defined as the maximum absolute difference between the gain at the frequency fo = 480 MHz and the gain
at the frequency fo = 480 MHz ±20 MHz. Where ∆Gv = maxG(fo ±∆f) − G(fo)
3. The unmatched noise figure (F) is measured at fi = 480 MHz in the application circuit (see Fig.6). With the hybrid
coupler used, the equivalent source impedance is equal to 100 Ω.
4. The minimum noise figure [F(min)] is measured at fi = 480 MHz with the input matching circuit shown in Fig.3;
(L1: 4.5 turns on, Φint = 3 mm, wire = 0.4 mm; L2: 11 turns on, Φint = 3 mm, wire = 0.4 mm).
5. The third-order intermodulation distance (IM3) is measured with an AGC voltage set to obtain a gain of −17 dB. The
input signal applied to the amplifier consists of two sine wave signals at fi = 479.5 MHz and fi = 480.5 MHz with an
amplitude equal to 90 dBµV for each tone.
6. The differential input impedance is represented by an equivalent parallel resistance and capacitance as shown in
Fig.1. The specified values are measured at fi = 480 MHz.
